What is a tissue fluid? One of the most important components of the body

The human body is one of the most difficultbuildings, which consists of many elements. In addition to internal organs, there is a huge number of connective parts, one of which is tissue fluid. It performs many important functions and is vital for every person.

Biological definition

What is a tissue fluid? It is this question that many people ask when they learn about the existence of this element. A sufficiently detailed answer was given by scientists who distinguished the definition of this part of the human body. Tissue fluid is one of the parts of the internal environment of the body, which is similar in composition to the plasma and fills all the distances between the cells. It includes cerebrospinal fluid and certain elements of the heart bag.

Education and Removal

For the most complete understanding of what istissue fluid, it is necessary to study the process of its appearance. This component occurs during the transformation of blood plasma, which penetrates through the walls of the capillaries into a special external space. It is during this period that the formation of a tissue fluid occurs, which remains between the cells. The unused portion of the plasma is returned back to the circulatory system.

What is tissue fluid

In the normal course of the life-support processThe tissue fluid accumulates in the lymphatic capillaries, from which it gradually passes into the vessels and serves as the main part of the lymph. After passing through all the stages, it flows through the lymph nodes and is involved in the process of blood circulation. This current occurs throughout the life of a person, supporting the work of all internal organs, enriching them with nutrients. The removal of this liquid occurs naturally as described above, but if this process slows down and it begins to accumulate, it is possible the appearance of disorders in the form of edema of various parts of the body. Everything depends on localization.

Disorders in the removal of tissue fluid

If the tissue fluid is not removed from the body at certain times, it stagnates. In the course of this, internal and external swelling is formed, which can be detected as follows:

  • With the initial stages of local edema, it is detected by pressing on the problem area, it forms a fossa that disappears long enough.
  • At a neglected stage, the swelling is visible to the naked eye.
  • The accumulation of fluid in the internal organs can be detected by systematic weighing.

what is the function of the tissue fluid

Types of local edema:

  • Allergic - arises from the reaction of the body to various pathogens, expressed as subcutaneous formations (urticaria, etc.), rarely affects the larynx, causing suffocation.
  • Edema caused by venous congestion.
  • Lymphatic stasis is the cause of the most dangerous edema. Initially, it is mild, but if you do not start treatment on time, you may develop an elephant disease.

General edema is formed with a large number of sodium ions and water in the body and is divided into the following types:

  • cordial;
  • hypoproteinemic;
  • renal;
  • fluid congestion in the lungs;
  • swelling of the brain.


For the most complete answer to the question about what is a tissue fluid, you need to consider its chemical composition:

  • water;
  • dissolved sugar, salt, amino acids, enzymes, etc .;
  • oxygen;
  • carbon dioxide;
  • residual effects of cell work.

formation of tissue fluid

In the tissue fluid contains very little protein - only 1.5 grams per 100 milliliters.


What is the function of the tissue fluid? It is the connecting element between the cells of the body and the blood vessels. Tissue fluid is located directly around the cells, ensuring the timely dissolution of membranes. Cells that come into contact with the tissue fluid receive from it all the necessary elements for nutrition and oxygen. In this case, the processed substances are returned back to the circulatory system and continue to circulate through the body. What is a tissue fluid? First of all, this is the most important element, acting as a link in the process of life-support of the whole organism.
