Internal organs of man: location, description

It is very important to know the location of all internalhuman organs. There is no need to carefully study this issue, enough generalized knowledge. They will allow you to easily navigate in different situations, when pain appears. Among the organs are those that relate to the thoracic and pelvic region. Others are located in the abdominal cavity. Next, consider the structure of man and internal organs. Photo clarifying schemes are available in the article.

Description of bodies

The human body is a complex mechanism,which consists of cells, tissues, organs located outside and inside. Some of them are known to every person. However, it should be noted that as long as the patient does not start to hurt something, he does not think about the state of his body. If you know where the various internal organs of a person are located, the structure of which is considered in this article, then it is possible to facilitate diagnosis in many diseases.

In an organism there are systems which have received the certain function. It should be noted: even though the bodies are united, they are not related.

In order to understand the subtleties of theissue, the article describes the structure of the internal organs of man. Photos are also attached to facilitate the perception. It is necessary to pay attention to the concept, which reveals all the issues related to the interior. Science, which tells about the cavities of the body, is called splanchnology.

The system of the abdominal organs includes several different structural units: intestine, pancreas, stomach, liver, diaphragm and gallbladder. Also add anus to this list.

Still there are genitourinary, urinary andreproductive system. This section of anatomy studies the endocrine glands that are near. The brain should also be attributed to the internal organs of man. In the skull is located the head, in the spine - the back. However, these structures are not studied in the sections of splanchnology.

Most of the organs form a certain system that functions together with the whole organism. There is digestive, endocrine, reproductive, nervous and so on.

Location of organs

Internal organs of a person, whose photospresented in the article, are located in certain cavities. For example, in the thoracic, you can find the chest, upper diaphragm, as well as the heart and two pleural branches. The stomach, kidneys, intestines, liver, pancreas and other organs are located in the abdominal region. They are a torso that is below the diaphragm. Thus, the described structure combines the abdominal and pelvic cavity. There are also reproductive system.

The internal organs of a person are divided into several categories, for example, there are smooth, parenchymal and dense.

If we talk about the former, they are created fromseveral layers, which doctors call shells. As a rule, such organs are covered with a special mucous surface, performing a protective function. Most organs have a similar coating in the form of folds, where there are outgrowths and grooves. However, there are also smooth mucous membranes. On some organs there is a muscle tissue that has received a longitudinal layer. It is separated by connective tissue. A man must have muscles of a smooth and striated type.

The first type, as a rule, is located ingenitourinary organs, and also in the respiratory tube. The latter are localized in the upper and lower parts of the body. Also, some groups have a special shell consisting of vessels and nerves.

The digestive system and all its organsserous coating, which is formed with the help of connective tissues. Due to the fact that they are smooth, all the insides can rub against each other.

Parenchymal organs have no cavity. They consist of parenchyma and stroma tissue.

Functionality and dimensions

All internal organs of man are not onlyspecial arrangement, but also functionality. If we talk about size, then there are small organs, for example, the adrenal glands. Of the large - the intestine. If you recall the brief course of anatomy in school, you can notice that the total weight of all the viscera can sometimes reach 20% of the total body weight. If we are talking about a person who has acute or chronic diseases, then this indicator is able to decrease or increase.

All bodies perform different functions, but theyare interconnected with each other. Many draw an analogy with musicians in the orchestra, who play under the conductor's conduct. The last thing in the body is the brain. There are no unnecessary musicians in the orchestra, so there are no superfluous organs in the human body. In the body all vital functions are realized.

System and apparatus

In addition, the featurescertain systems. For example, a skeleton is a musculoskeletal system, which consists of tendons, bones, joints, and muscles. It depends on him the proportions of the body, as well as how the person will move.

In the cardiovascular system there are organs,which provide the movement of blood, which allows you to saturate cells with oxygen. The most important in this system is the heart, which pumps blood.

The lymphatic structure consists of vessels,trunks, capillaries and so on. Due to the presence of a small pressure, the liquid moves without problems on the tubes. This system is responsible for excretion of waste products from the body.

All internal bodies are regulated by the National Assembly, whichis divided into 2 types: central and peripheral. The most important in the first system are the brain and spinal cord. Peripheral consists of nerves, endings and so on.


Internal organs are the basis of life.To exist without limbs a person is capable, however without a liver or heart it is impossible. Accordingly, there are organs that provide life activity, as well as those without which you can do without. Certain structures are able to regenerate, for example, the liver. There are also organs whose function is performed by paired structures. An example of such are the kidneys. The human body is a rather complex system, so people should always take care of it and monitor the condition. Do not neglect elementary things, you should support the body in order. Otherwise, before the time, it will begin to wear out. The article contains a photo describing the internal organs of a person, which will allow us to better understand this question.
