The organs of the abdominal cavity are what every person has and invariably, day after day, ensures the normal coordinated work of the body. Unfortunately, very few people know what is the scheme or where are these or those internal organs, their departments, and what is their structure in general?

Location of the abdominal organs

The organs of the abdominal cavity include the following systems: the kidneys and adrenal glands, the gallbladder and ureter, as well as the liver, spleen and the entire gastrointestinal tract. In front and on the sides, their location is limited by the abdominal wall, which is permeated with muscles, as well as fatty tissue and connective tissue formations that are present in every person without exception, which can be seen in all the pictures.

In general, the abdominal cavity can be described as all the space that is under the diaphragm. It is in it that all organs are concentrated, and the abdominal region passes into the pelvic region. The space behind the peritoneum is characterized by the fact that it is covered with a serous membrane, which extends to all the internal organs of a person.

It should be noted that due to some physiological features, the friction of the surfaces of the internal organs against each other does not occur. A similar effect is achieved due to the presence of an epithelial cover, as well as a serous fluid that complements the structure, as can be seen in the pictures and photos. The separator of the organs that belong to the chest and abdominal cavity is the diaphragm, the location of which is always the same.

In the upper region of the peritoneum is the stomach and its departments that contain food. It is known that it is its quantity that directly affects the size of this human organ. By itself, the stomach resembles a small pouch that has a specific outlet, namely a tube, which is known as the intestine.

Certain functions are assigned to it, for example, the absorption of the main part of the nutritional components.

The presented sections of the gastrointestinal tract in any person end with an anus, which is obvious in any photo or picture. Experts point out the following features that determine the structure of this system:

1. The spleen belongs to the organs of the abdominal cavity and the space behind the peritoneum. This happens despite the fact that it belongs to the lymphatic system, but it can be detected (for example, during ultrasound) under the left hypochondrium;
2. the upper part of the abdominal region is occupied by the liver, which is attached to the diaphragm, stomach, as well as the intestines and abdominal wall through ligaments. It is she who is responsible for the formation and secretion of bile and similar components;
3. the preservation of the location of all internal organs of a person is ensured by the abdominal press. This is most relevant in a vertical position.

It should be noted that the internal organs have even more specific protection, namely that which is provided by the bones. From the back, this is the spinal column and pelvic bones, in front - exclusively muscles. There are other forms of protection that allow you to survive and cope with any extreme situations and even injuries. It should also be noted that it is possible to control how correct the structure of the internal organs of a person is, whether certain departments work correctly with the help of ultrasound. This method is 100% effective. About some differences between men and women in the structure of the internal organs of the abdominal cavity - further.

Differences in the structure of internal organs between men and women

Before moving on to the structural features of the internal organs of males and females, which are visible even in the paintings, I would like to draw attention to some other points. In particular, the fact that a characteristic feature of the structure of the peritoneal organs should be considered a covering of a very thin serous membrane. We are talking about mesothelial tissue, which has a significant amount of strong fibers.

In addition, the mesothelium ensures the production of lubrication, reduces the friction of organs - it is precisely due to this feature that characterizes the structure of a person that we do not experience painful and simply unpleasant sensations.

Such pains can manifest themselves only in diseases or inflammatory conditions, infectious lesions.

Speaking directly about the female representatives, it is necessary to pay attention to the fact that one of the main differences is the presence of tubes in the pelvic area that communicate directly with the uterus. Through the vagina, the sexual sphere gets the opportunity to communicate with external environment which is obvious in the pictures. It is possible to fix certain internal female organs of the reproductive system, as well as the prostate gland in men, when performing ultrasound of the human peritoneal organs, which also demonstrates some other departments.

If we talk specifically about the organs of the abdominal cavity of the male representatives, then they are located exclusively in a closed space. However, regardless of the gender of a person, the internal organs and their structure are always determined by the presence of a serous membrane. The difference lies only in whether one or another internal area is partially covered or the film is located on the entire surface part.

In general, the placement of the organs of the peritoneum and the space behind the peritoneum is possible in three ways. The first is extraperitoneal, which is characterized by the fact that the peritoneum covers the insides exclusively in front. This is characteristic of the kidneys. Further, to the second option, experts rank mesoperitoneal, within the framework of the development of which only three sides of one or another inside have a coating, and the fourth remains uncovered. The most characteristic example is the liver, which is almost completely covered with a serous membrane.

The third option is intraperitoneal, which is characterized by the fitting of the organ by the abdominal region from all sides. One example of this is the small intestine. About how exactly the diagnosis of the internal organs of a person is carried out, how their structure is determined and much more, further.

How is the abdominal cavity diagnosed?

In order to 100% accurately determine the location and any other features of the abdominal organs in men and women, it is necessary to attend to a diagnostic examination. The main technique is ultrasound, due to which, as in the pictures, it turns out to be obvious, for example, the key causes of pain in the abdomen. In addition, the state of the gallbladder, liver is assessed, the pancreas and aorta are examined.

The specialist gets the opportunity to visually verify whether the stones are in the bile ducts, whether it is possible to confirm the existing suspicion of ascites. In addition, it is the presented method of examination, as in the pictures, that reveals an organic lesion of the kidneys and an acute form of appendicitis. On ultrasound, it is ideal to view the topography of the peritoneal organs.

In general, as experts note, the procedure is completely harmless and safe, it is permissible to carry it out quite often, due to the absence of the influence of ultrasonic waves on the structural structure of cells.

To judge how correctly the peritoneal organs are located, to determine the degree of development of pathological conditions, specialists can perform not only ultrasound, but also CT or MRI. The presented diagnostic techniques easily identify focal lesions, as well as fatty liver regeneration, dystrophic and ischemic algorithms, which can become more intense with age.

At the same time, for example, stones (deposits of calcium salts) cannot be fixed on MRI images and pictures. In the vast majority of cases, their cost is approximately comparable to the implementation of a diagnostic examination through ultrasound.

Considering all this, it is safe to say that today specialists know everything about the structure of not only internal organs, but also all those structures that enter the abdominal cavity. It is they who provide 100% coordinated work of the body, fully providing all physiological processes.

1. Can cancer be prevented?
The occurrence of a disease such as cancer depends on many factors. No one can be completely safe. But everyone can significantly reduce the chances of a malignant tumor.

2. How does smoking affect the development of cancer?
Absolutely, categorically ban yourself from smoking. This truth is already tired of everyone. But quitting smoking reduces the risk of developing all types of cancer. Smoking is associated with 30% of cancer deaths. In Russia, lung tumors kill more people than tumors of all other organs.
Eliminating tobacco from your life is the best prevention. Even if you smoke not a pack a day, but only half, the risk of lung cancer is already reduced by 27%, as the American Medical Association found.

3. Does excess weight affect the development of cancer?
Keep your eyes on the scales! Extra pounds will affect not only the waist. The American Institute for Cancer Research has found that obesity contributes to the development of tumors in the esophagus, kidneys, and gallbladder. The fact is that adipose tissue serves not only to store energy reserves, it also has a secretory function: fat produces proteins that affect the development of a chronic inflammatory process in the body. And oncological diseases just appear against the background of inflammation. In Russia, 26% of all cancer cases are associated with obesity.

4. Does exercise help reduce the risk of cancer?
Set aside at least half an hour a week for exercise. Sport is on the same level as proper nutrition when it comes to cancer prevention. In the US, a third of all deaths are attributed to the fact that patients did not follow any diet and did not pay attention to physical education. The American Cancer Society recommends exercising 150 minutes a week at a moderate pace or half as much but more vigorously. However, a study published in the journal Nutrition and Cancer in 2010 proves that even 30 minutes is enough to reduce the risk of breast cancer (which affects one in eight women in the world) by 35%.

5.How does alcohol affect cancer cells?
Less alcohol! Alcohol is blamed for causing tumors in the mouth, larynx, liver, rectum, and mammary glands. Ethyl alcohol breaks down in the body to acetaldehyde, which then, under the action of enzymes, turns into acetic acid. Acetaldehyde is the strongest carcinogen. Alcohol is especially harmful to women, as it stimulates the production of estrogen - hormones that affect the growth of breast tissue. Excess estrogen leads to the formation of breast tumors, which means that every extra sip of alcohol increases the risk of getting sick.

6. Which cabbage helps fight cancer?
Love broccoli. Vegetables are not only part of a healthy diet, they also help fight cancer. This is also why recommendations for healthy eating contain the rule: half of the daily diet should be vegetables and fruits. Especially useful are cruciferous vegetables, which contain glucosinolates - substances that, when processed, acquire anti-cancer properties. These vegetables include cabbage: ordinary white cabbage, Brussels sprouts and broccoli.

7. Which organ cancer is affected by red meat?
The more vegetables you eat, the less red meat you put on your plate. Studies have confirmed that people who eat more than 500 grams of red meat per week have a higher risk of developing colon cancer.

8. Which of the proposed remedies protect against skin cancer?
Stock up on sunscreen! Women aged 18-36 are particularly susceptible to melanoma, the deadliest form of skin cancer. In Russia, in just 10 years, the incidence of melanoma has increased by 26%, world statistics show an even greater increase. Both artificial tanning equipment and the sun's rays are blamed for this. The danger can be minimized with a simple tube of sunscreen. A study published in the Journal of Clinical Oncology in 2010 confirmed that people who regularly apply a special cream get melanoma half as often as those who neglect such cosmetics.
The cream should be chosen with a protection factor SPF 15, apply it even in winter and even in cloudy weather (the procedure should turn into the same habit as brushing your teeth), and also do not expose yourself to the sun's rays from 10 to 16 hours.

9. Do you think stress affects the development of cancer?
By itself, stress does not cause cancer, but it weakens the entire body and creates conditions for the development of this disease. Research has shown that constant worry alters the activity of the immune cells responsible for turning on the fight-and-flight mechanism. As a result, a large amount of cortisol, monocytes and neutrophils, which are responsible for inflammatory processes, constantly circulate in the blood. And as already mentioned, chronic inflammatory processes can lead to the formation of cancer cells.

Man still remains an exceptionally complex structured organism on the planet. Our body is a unique system in which all its parts work together and perform a number of functions simultaneously. Each organ in our body has its own task and performs it: the lungs enrich blood cells with oxygen, the heart drives oxygenated blood around the body to deliver it to every cell, the brain controls all cognitive processes.

The structure of both internal organs and the whole organism is studied by human anatomy, which is divided into internal and external.

The external structure of a person combines those parts of the body that we can see with our own eyes without any adaptations. The external anatomical structure includes such organs as the head, neck, torso, chest, back, upper and lower limbs. Internal anatomy describes the location in the body of the internal organs of a person, they cannot be seen with the naked eye.

The structure of our body is in many ways the same as that of mammals. This fact is easy to explain, since according to evolutionary theory, a person can be one of the branches of the development of mammals. Man developed simultaneously with animals in similar natural conditions, which ensured similarities in the structure of cells, tissues, internal organs and their systems.

The structure of internal organs: the brain

The brain is the most complex internal organ, the complex structure of which puts us several steps higher in development than all other creatures on the planet. The brain and a complex of neurons is the central nervous system, under the control of which are all the functions of the body, and the thought process is provided. The brain is positioned as a collection of nerve fibers that form a complex stable system. It includes the two cerebral hemispheres, the cerebellum and the pons.

Even now, experts say that the human brain is not even half understood. During the formation of anatomy as a science, the greatest difficulties arose precisely with the description of the processes occurring in the nervous tissue that forms the brain.

Main parts of the brain:

• Large hemispheres occupy the largest part of the volume of the brain. Through them, control occurs at all stages of thought processes. It is thanks to the action of the large hemispheres that we make conscious movements;
• Two variolius bridges. One of the bridges is located under the cerebellum almost at the base of the skull and performs the task of receiving and transmitting nerve impulses. The second bridge is located even lower, has an oblong shape and provides signal transmission from the spinal cord;
• Cerebellum. A significant part of the brain, which determines the ability to keep the body in balance. Controls muscle reflexes. For example, when touching something hot, we withdraw our hand even before we are aware of what has happened. It is these reflexes that are controlled by the cerebellum.

Human abdominal organs

The abdominal cavity is defined as the space that the diaphragm delimits from the chest cavity from above, it is closed in front and from the sides by the abdominal muscles, and behind it is protected by the spinal column and the muscle tissues located there. The abdominal cavity is also called the abdominal cavity.

From below, the abdominal cavity smoothly passes to the cavity of the small pelvis. Here is a complex of internal organs that perform various important functions, as well as nerve endings and large blood vessels. Diseases of the abdominal organs are the most common cases in practical medicine and have a great impact on the entire human body, so the speed of making the correct diagnosis and the patient's life depend on knowledge about them.

Part of the organs located inside the abdominal cavity are completely or partially covered with a special membrane, but some of them do not have it at all.

This shell has considerable elasticity and is characterized by a specific ability to absorb. Serous fluid is produced here, which, acting as a lubricant, reduces the amount of friction between the organs.

The organs of the abdominal cavity

• Stomach- a muscular organ shaped like a bag. This is one of the main organs of the food digestion system, which is essentially a continuation of the esophagus in the abdominal cavity. The walls of the stomach produce a special complex of biologically active substances and enzymes, which is called gastric juice, which actively breaks down nutrients. The acidity of gastric juice can show the state of the entire gastrointestinal tract as a whole.
• Intestines. This is the longest part of the digestive system. It begins with the outlet of the stomach and ends with the excretory system. Inside the abdominal cavity, the intestines are in the form of peculiar loops. The main task of this organ is the digestion of food and the removal of unnecessary substances from the body. The intestine is subdivided into the large intestine, small intestine and rectum.
• kidneys- as well as the lungs, a paired organ, which is localized in the lumbar region and, if you look at the photo, resemble beans in shape. They ensure the maintenance of homeostatic balance in the body, and are also part of the urinary system.
• adrenal glands. The satellite organs of the kidneys, also paired, are located on the right and left in the abdominal cavity. Their main task is to regulate the functionality of the endocrine and hormonal systems. The adrenal glands produce a large number of hormones - more than 25, which include adrenaline, corticosteroids and other substances. Impulses from the nervous system are also transmitted to the adrenal glands, which are picked up by the medulla that fills these organs. Here there is a regulation of the processes of inhibition and excitation, characteristic of stressful conditions.
• Liver known as the largest gland in our body. Its placement is directly below the diaphragm and is divided into two lobes. In the liver, toxic and harmful substances are neutralized, therefore it is the first organ that suffers when a person has bad habits. Also, the liver takes part in blood circulation and affects the digestive processes. In the process of functioning, there is a close relationship between the liver and the gallbladder.
• Bladder also located in the abdominal cavity and is a kind of bag in which urine accumulates, subsequently excreted from the body by the efforts of the excretory system. The bladder is located in the groin behind the pubic bone. Also, the bladder has a significant impact on digestion. Violations in its work can lead to such unpleasant consequences as discomfort, nausea and vomiting. It also often leads to the development of stomach and intestinal ulcers.
• Pancreas. It has the ability to produce special substances and enzymes that improve the speed and quality of food digestion. This organ is located on the left behind the stomach, in the upper half of the abdominal cavity. One of its main tasks is to provide the body with a natural hormone - insulin. If the pancreas function is impaired, diabetes mellitus develops.

An important hematopoietic organ of the abdominal cavity is the spleen, if you look at the model of a person with organs, it can be found above the diaphragm. This is a unique organ that has the ability to change its size depending on the volume of blood flow. The spleen also performs a protective function in the body.

Significant differences in the structure of the male and female abdominal cavity

The layout of the abdominal organs has an unchanged structure, characteristic of any person of any nationality. Some structural features stand out in childhood and adulthood, but the largest part of the differences is determined by sex.

In men, the abdominal cavity is defined as a closed system, but in women it is not a closed space, since in the female body there is communication with the uterine region using the fallopian tubes. In addition, in the female body, the abdominal cavity is able to communicate with the external environment through the vaginal cavity.

The organs of the chest

The chest is the most important protective structure in our body, which protects the most significant organ in the human body - the heart and the largest blood vessels that go to it. Most of the chest cavity is occupied by the lungs, which provide oxygen saturation of the blood and removal of carbon dioxide harmful to the body. Also here is the diaphragm, which is a flat wide muscle, one of the functions of which is to distinguish between the chest and the abdominal cavity. Let us consider in more detail the location of human organs located in the chest cavity.

The heart is a hollow muscular organ located in the chest between the lungs with a shift to the left side. It is easy to imagine the size of the heart if you squeeze the hand of an adult into a fist. On the one hand, the heart performs one simple function - it pumps blood into the arteries and receives venous blood, on the other hand, our body could not exist without this function.

Basic facts about the structure and work of the heart

• The movements necessary to pump blood into the vessels are produced by the heart through the work of the left and right ventricles;
• The layout of the heart inside the chest is very curious and is called oblique presentation. This means that the narrower part of this organ looks down and to the left, and the wider part up and to the right;
• The right ventricle of the heart is somewhat smaller than the left;
• The main vessels depart from the wide part of the heart (or its base). The heart is never at rest, as it needs to constantly pump blood into the vessels, which carries oxygen and nutrients to all cells of the body;
• Outside, this muscular organ is covered with the pericardium - a special type of tissue, in the outer part of which blood vessels are located. The inner layer of the pericardium adheres tightly to the heart.

The structure of the lungs

The lungs are the largest paired organ not only located in the chest cavity, but also in the whole human body. Both lungs - left and right, are identical in appearance, but nevertheless, their anatomy and functions have significant differences.

The left lung can be subdivided into just two lobes, while the right is subdivided into as many as three. Also, the lung, located in the chest on the left, is distinguished by the presence of a bend. The main task of the lungs remains the processing and saturation of blood cells with oxygen, as well as the removal of carbon dioxide formed during respiration, the presence of which is dangerous for the whole organism.

Also located in the chest cavity is the trachea, which acts as an air duct through which oxygen enters the lungs. It is located from top to bottom and connects the larynx with the bronchi. This organ is a complex of cartilaginous half-rings and connective ligaments, on the back wall of the trachea there is muscle tissue covered with mucus. The trachea in the lower section is subdivided into bronchi, which in essence represent its continuation. Air enters the lungs through the bronchi. In the internal composition of the lung there are many bronchi, whose branches represent a complex structure. The trachea also performs protective and cleansing functions.

The esophagus is also located in the chest cavity - a muscular organ that connects the larynx to the stomach and ensures the intake of food.

Taking care of the body is the key to health

Despite the vast knowledge of mankind and its own anatomy, the human body still remains the most important object of study and experimentation. We have not yet solved all of its riddles, there are a great many of them ahead.

At the same time, the instinct of self-preservation, protection of the whole organism and internal organs is inherent in all living beings from the very beginning. However, a person often forgets to treat his body with due respect. Not only leading an unhealthy lifestyle and having bad habits, but also engaging in hard physical labor or other situations that require the body to work to the limit, can cause malfunctions and the functioning of internal organs and lead to diseases. Therefore, do not forget about respect for your body.

Schemes of the location of the internal organs of a person with inscriptions by zones.

Knowledge of the structure of the body is the key to understanding the processes occurring in it and malfunctions.

The set of mandatory knowledge for a person is constantly expanding. However, without a clear understanding of the functioning of the body, its needs and the relationship of organs, all other achievements of science and progress are useless.

Thoroughly in detail anatomy is studied by students of medical universities. It is enough for an average adult to have an idea about the location of organs inside himself at the level of the school curriculum.

We invite you to refresh your knowledge in this area.

Location of human organs: photo with inscriptions

The internal organs of the human body are compactly placed in the torso in conditional zones:

• chest
• abdominal
• large and small pelvis

The first zone is separated from the second by a diaphragm. The second and third zones do not have such a clear boundary.

The thoracic region, in turn, consists of:

• 2 lung spaces
• heart zone

The abdominal cavity is also divided into 2 components:

• directly abdominal
• retroperitoneal

Their functional tasks are fundamentally different from each other and at the same time are closely related.

So the chest organs are responsible for:

• breath
• oxygen uptake and waste air removal
• blood pumping

The organs of the abdominal cavity provide:

• digestive processes
• absorption of nutrients
• strength of immunity
• filtration of toxins, poisons
• participation in the hematopoiesis of your body, and in the female version - the fetus
• formation of acids for digestion
• hormonal regulation of the correct functioning of all organs of the abdominal region

In the large and small pelvis, their tasks are carried out:

• excretion of waste substances
• reproduction
• hormonal control of the work of the organs of the considered zone

According to the structure and appearance, the internal organs are divided into:

• tubular, or hollow - for example, the stomach
• whole, without a cavity - for example, the liver

• muscles cause organ contractions,
• mucous membranes - moisturizing and absorbing substances,
• slippery outer layer - the absence of friction between the organs.

In our body, part of the organs are paired, for example, the lungs, part without a pair, for example, the heart.

See the internal structure of the human body in the photo below.

What organs are located in the chest: a diagram with inscriptions

The chest is the location of the respiratory organs, in particular the lungs.

• They occupy almost all of its space, especially at the time of inspiration. From below, the lungs rest against the diaphragm. Around them - protection from the ribs.
• The bronchial tree branches inside the lungs and connects them to the trachea.
• Moreover, its left branch is thinner and longer than the right one.

The heart is your body's motor that pumps blood through a network of blood vessels. It is located between the lungs above the diaphragm, has a slight tilt back. 2/3 of the heart is on the left side of the center of the chest, and 1/3 on the right.

The thymus gland is the mysterious organ of the chest. It is located in the upper part of the latter above the bronchial branching into the lungs. Participates in the work of the human immune system.

On the diagram of the organs of the chest, consider their location.

What organs are located in the abdominal cavity: a diagram with inscriptions

The abdomen is filled large quantity organs than the previous one. Consider their placement according to 3 parameters:

• in the center
• to his right
• left

• The small intestine looks like a thin tangled tube. It is formed at the site of narrowing of the stomach and is capable of reaching 6 m in length. It expands smoothly into the large intestine at the bottom right. The latter forms a semicircle clockwise around the entire space of the abdominal cavity and ends with the anus.

The intestine is the most important organ of the immune system. Thanks to its ability to pulsating compression, poisons, toxins, and harmful substances are removed from the body.

The stomach is an expansion of the esophagus, resembling a bag. It is located just below the diaphragm.

• As it fills, it is able to change its size. People with an addiction to eating large amounts of food have an enlarged stomach.
• It is a reservoir for the accumulation and digestion of food, passing through the first stage of the absorption of nutrients.

The stomach is a complete organ with several layers of muscles. Due to the reduction of the latter, food moves through the organ and further into the intestines.

The pancreas is located slightly lower under the stomach. She:

• participates in the process of digestion of food,
• produces juice for its splitting,
• provides metabolic processes in the body, namely protein-carbon and fat.

The spleen provides hematopoiesis for adults and fetuses in women. It is located behind the stomach. In appearance - an incomplete dense hemisphere.

Spleen:

• responsible for the production of lymphocytes
• accumulates platelets
• captures harmful substances and bacteria, filters them
• participant in the body's metabolic processes
• ambulance for erythrocytes and platelets with damaged membranes

The liver is a vital human organ. It consists of 2 lobes, of which the right is much smaller than the left.

The task of neutralizing poisonous and toxic compounds with their subsequent removal from the body lies on the liver. As well as:

• maintenance of lipid balance
• absorption of cholesterol and glucose
• withdrawal of excessive amounts of vitamins and substances of internal metabolism

The gallbladder is a small pear-shaped sac located under the right lobe of the liver.

Its task is to accumulate bile coming from the liver and send it to the intestines. It helps to qualitatively digest food at all stages of its movement, starting from the stomach.

On both sides are the kidneys and adrenal glands.

Kidneys are shaped like beans.

• They are located behind the organs of the abdominal cavity closer to the lumbar zone.
• The right kidney is smaller than the left. The weight of one varies between 100-190 gr, and the size is about 10 cm.
• The purpose of the kidneys is to filter and secrete urine, regulate chemical processes.

Adrenal glands are paired glands, representatives of the endocrine system. Responsible for regulating hormone levels:

• adrenaline
• sex - androgens
• corticosteroids
• cortisone and cortisol
• norepinephrine

The adrenal glands help a person adapt to new living conditions and cope with stressful situations.

A diagram will help you visually remember the location of the abdominal organs.

The structure of the pelvic organs: a diagram with inscriptions

Since people are divided into two groups by gender, the set of organs of the small pelvis is not the same for us.

In the pelvis are located:

• bladder and rectum - common
• uterus and ovaries - in women
• prostate and testicles in men

Let's take a closer look at the first two.

The bladder leans on the pubic area. In an empty state, it seems to spread out, and in a filled state it has the shape of an oval container.

Its task is to accumulate fluid from the kidneys and remove it from the body through the ureters.

The rectum is a continuation of the large intestine. It is located vertically down the far wall of the small pelvis.

Its task is to collect and withdraw waste material after the digestion process.

Between the bladder and the rectum are:

• uterus in women
• prostate in men

The diagram with the location of the pelvic organs is presented below.

So, we examined the anatomical location of the internal organs of a person, got acquainted with their main tasks and activities.

Study the structure of your body consciously. Learn to listen to his needs and live in harmony with him!

Video: Human Anatomy. Where and what is located?

All organs of the human body have an individual structure and location. They perform a vital role in maintaining the normal functioning of the body on a daily basis. It is important to know the location of the main organs in order to cope with any complications, injuries, or accurately determine the profile of the doctor to whom you need to seek help.

Under the thyroid cartilage of the larynx (Adam's apple), on the front side of the neck below, is the thyroid gland. With age, the gland can fall lower, sometimes deepening into the chest cavity. The thoracic and abdominal cavities of the body are separated by a muscular organ-diaphragm. In the chest, between the left and right lungs behind the sternum and above the diaphragm, is the heart. 2/3 of the body is located on the left side of the body, and 1/3 - on the right. A pair of lungs occupies most of the space inside the chest cavity. They run transversely from the heart to the ribs on both sides of the chest and continue behind towards the spine. The bases of the lungs rest against the domed diaphragm. Behind the sternum and above the heart, in the mediastinum of the chest cavity is the thymus gland. The main reservoir for food storage is the stomach. It lies in the shape of a crescent under the diaphragm on the left side of the abdominal cavity. Behind and below the stomach on the left side of the abdominal cavity is the pancreas, which is involved in the breakdown of proteins, fats, carbohydrates and secretes the hormones insulin and glucagon. The liver is located in the right upper part of the abdominal cavity under the diaphragm. Most of its mass falls on the right lobe, where it descends towards the right kidney. In the right hypochondrium in the deepening of the lower surface of the liver is the gallbladder, which plays an important role in the digestion of food. Between the stomach and the diaphragm in the left hypochondrium of the abdominal cavity, under the protection of the ribs, lies the spleen, which takes part in protecting the human body from infections and blood loss. The small intestine is a long, intricate tube that occupies a peritoneal position below the stomach. The large intestine originates on the right side of the human body. Further, it flows around the border of the abdominal cavity at the top and descends down the left side. The beginning of the large intestine (caecum) has a vermiform process - the appendix. The large intestine ends at the anus (anus), through which feces exit. Paired organs of the genitourinary system - the kidneys - lie along the posterior muscular wall of the abdominal cavity. They are located behind the peritoneum, which lines the abdominal cavity. The left kidney is slightly higher than the right one due to the enlargement of the liver on the right side of the body. At the top of each kidney, at the level of 11-12 thoracic and 1 lumbar vertebrae, lie the adrenal glands. They release over 30 vital hormones directly into the bloodstream. At the bottom of the pelvis is the bladder. In the representatives of the stronger sex, the seminal vesicles and the rectum are located behind the bladder, under it is the prostate gland. In women, behind the bladder is the vagina, under the body - the muscles of the pelvic floor. The ovaries are a pair of tiny glands in the female body. They lie on opposite sides of the uterus in the pelvic cavity and are attached to the wall of the uterus by ligaments. The uterus is a hollow muscular organ of the female reproductive system, located above the bladder and in front of the rectum, in the middle part of the pelvic cavity. The testes (testes) are a pair of oval glandular organs of the male reproductive system, which are located in the scrotum. Below Bladder in the form of a rounded cone or funnel lies the prostate gland.

The above description of the location of the main internal organs of the human body makes it possible to better understand the structure of your body and determine the organ in which changes have begun to occur.

Knowing the structure and location of internal organs is extremely important. Even if you do not study this issue thoroughly, then at least a superficial understanding of where and how this or that organ is located will help you quickly navigate when pain occurs and at the same time react correctly. Among the internal organs, there are both organs of the chest and pelvic cavity, and organs of the abdominal cavity of a person. Their location, diagrams and general information presented in this article.

Organs

The human body is a complex mechanism, consisting of a huge number of cells that form tissues. From their separate groups, organs are obtained, which are commonly called internal, since the location of organs in humans is inside.

Many of them are known to almost everyone. And in most cases, until somewhere it hurts, people, as a rule, do not think about what is inside them. Nevertheless, even if the layout of human organs is only superficially familiar, in the event of a disease, this knowledge will greatly simplify the explanation to the doctor. Also, the recommendations of the latter will become more understandable.

Organ system and apparatus

The concept of a system refers to a specific group of organs that has anatomical and embryological kinship and also performs a single function.

In turn, the apparatus, whose organs are closely interconnected, has no kinship inherent in the system.

Splanchnology

The study and location of organs in humans are considered by anatomy in a special section called splanchnology, the study of the insides. We are talking about the structures that are in the body cavities.

First of all, these are the organs of the human abdominal cavity involved in digestion, the location of which is as follows.

Next comes the genitourinary, urinary and reproductive systems. The section also studies the endocrine glands located next to these systems.

The internal organs also include the brain. In the cranium is the head, and in the spinal canal - the dorsal. But within the limits of the section under consideration, these structures are not studied.

All organs appear as systems functioning in full interaction with the whole organism. There are respiratory, urinary, digestive, endocrine, reproductive, nervous and other systems.

Location of organs in humans

They are in several specific cavities.

So, in the chest, located within the boundaries of the chest and the upper diaphragm, there are three others. This is a pelicard with a heart and two pleurals on both sides with lungs.

The abdominal cavity contains the kidneys, stomach, most of the intestines, liver, pancreas and other organs. It is a body located below the diaphragm. It includes the abdominal and pelvic cavities.

The abdomen is divided into the retroperitoneal space and the peritoneal cavity. The pelvis contains the excretory and reproductive systems.

To understand in more detail the location of human organs, the photo below serves as an addition to the above. On one side, it depicts cavities, and on the other, the main organs that are located in them.

The structure and layout of human organs

The first in their tubes have several layers, which are also called shells. The inside is lined with a mucous membrane, which plays mainly a protective function. Most organs on it have folds with outgrowths and depressions. But there are also completely smooth mucous membranes.

In addition to them, there is a muscular membrane with circular and longitudinal layers separated by connective tissue.

On the human body there are smooth and striated muscles. Smooth - prevail in the respiratory tube, urinary organs. In the digestive tube, striated muscles are located in the upper and lower sections.

In some groups of organs there is another shell, where the vessels and nerves pass.

All components of the digestive system and lungs have a serous membrane, which is formed by connective tissue. It is smooth, thanks to which there is an easy sliding of the insides against each other.

Parenchymal organs, unlike the previous ones, do not have a cavity. They contain functional (parenchyma) and connective (stroma) tissues. The cells that perform the main tasks form the parenchyma, and the soft framework of the organ is formed by the stroma.

Male and female organs

With the exception of the sex organs, the arrangement of human organs - both men and women - is the same. In the female body, for example, are the vagina, uterus and ovaries. In the male - the prostate gland, seminal vesicles and so on.

In addition, male organs tend to be larger than female organs and therefore weigh more. Although, of course, it also occurs vice versa, when women have large forms, and men are small.

Dimensions and functions

As the location of human organs has its own characteristics, so does their size. Of the small ones, for example, the adrenal glands stand out, and of the large ones, the intestines.

As is known from anatomy and shows the location of human organs in the photo above, the total weight of the viscera can be about twenty percent of the total body weight.

In the presence of various diseases, the size and weight can both decrease and increase.

The functions of the organs are different, but they are closely interconnected with each other. They can be compared to musicians playing their instruments under the control of a conductor - the brain. There are no unnecessary musicians in an orchestra. Also, however, in the human body there is not a single superfluous structure and system.

For example, due to respiration, the digestive and excretory systems, the exchange between the external environment and the body is realized. The reproductive organs provide reproduction.

All of these systems are vital.

Systems and Apparatus

Consider the common features of individual systems.

The skeleton is the musculoskeletal system, which includes all the bones, tendons, joints and somatic muscles. Both the proportion of the body and the movement and locomotion depend on it.

The location of organs in a person of the cardiovascular system ensures the movement of blood through the veins and arteries, saturating the cells with oxygen and nutrients, on the one hand, and removing carbon dioxide with other waste substances from the body, on the other. The main organ here is the heart, which constantly pumps blood through the vessels.

The lymphatic system consists of vessels, capillaries, ducts, trunks and nodes. Under slight pressure, the lymph moves through the tubes, ensuring the removal of waste products.

All internal organs of a person, the layout of which is given below, are regulated by the nervous system, which consists of a central and peripheral sections. The main part includes the spinal cord and brain. Peripheral consists of nerves, plexuses, roots, ganglia and nerve endings.

The functions of the system are vegetative (responsible for the transmission of impulses) and somatic (connecting the brain with the skin and ODP).

The sensory system plays the main role in fixing the reaction to external stimuli and changes. It includes the nose, tongue, ears, eyes and skin. Its occurrence is the result of the work of the nervous system.

The endocrine system, together with the nervous system, regulates internal reactions and sensations of the environment. Emotions, mental activity, development, growth, puberty depend on her work.

The main organs in it are the thyroid and pancreas, testicles or ovaries, adrenal glands, pineal gland, pituitary gland and thymus.

The reproductive system is responsible for reproduction.

The urinary system is located entirely in the pelvic cavity. It, like the previous one, differs depending on gender. The need for the system is to remove toxic and foreign compounds, an excess of various substances through the urine. The urinary system consists of the kidneys, urethra, ureters, and bladder.

The digestive system is the human internal organs located in the abdominal cavity. Their layout is as follows:

Its function, logically coming from the name, is to extract and deliver nutrients to cells. The location of the human abdominal organs gives a general idea of ​​the process of digestion. It consists of mechanical and chemical processing of food, absorption, breakdown and excretion of waste products from the body.

The respiratory system consists of the upper (nasopharynx) and lower (larynx, bronchi and trachea) sections.

The immune system is the body's defense against tumors and pathogens. It consists of thymus, lymphoid tissue, spleen and lymph nodes.

The skin protects the body from temperature extremes, drying out, damage and the penetration of pathogens and toxins into it. It consists of skin, nails, hair, sebaceous and sweat glands.

Internal organs - the basis of life

The photo shows the location of the internal organs of a person with a description.

We can say that they are the basis of life. It is difficult to live without lower or upper limbs, but still possible. But without a heart or a liver, a person cannot live at all.

Thus, there are organs that are vital, and there are those without which life is difficult, nevertheless possible.

At the same time, some of the first components have a paired structure, and without one of them, the entire function passes to the remaining part (for example, the kidneys).

Some structures are able to regenerate (this applies to the liver).

Nature has endowed the human body with the most complex system, to which it must be attentive and protect what is given to it in the allotted time.

Many people neglect the most elementary things that can keep the body in order. Because of this, it becomes unusable ahead of time. Diseases appear and a person passes away when he has not yet done all the things that he should have done.
