The human body is one of the most complex structures, which consists of many elements. In addition to internal organs, there are a huge number of connecting parts, one of which is tissue fluid. It performs many important functions and is vital for every person.
Biological definition
What is tissue fluid? It is this question that many people ask when they learn about the existence of this element. A fairly detailed answer was given by scientists who identified the definition of this part of the human body. Tissue fluid is one of the parts of the body's internal environment, which is similar in composition to plasma and fills all the distances between cells. This includes cerebrospinal fluid and certain elements of the heart sac.
Education and removal
For the most complete understanding of what tissue fluid is, it is necessary to study the process of its appearance. This component arises in the process of transformation of blood plasma, which penetrates through the walls of capillaries into a specialouter space. It is during this period that the formation of tissue fluid occurs, which remains between the cells. The unused part of the plasma is returned back to the circulatory system.
In the normal course of the life support process, 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 flow occurs throughout a person's life, supporting the work of all internal organs, enriching them with nutrients. The removal of this fluid occurs naturally, as described above, but if this process is inhibited and it begins to accumulate, disturbances in the form of edema of various parts of the body may occur. It all depends on the localization.
Disturbances in the removal of tissue fluid
If the tissue fluid is not excreted from the body within a certain period of time, it stagnates. During this, internal and external edema is formed, which can be detected as follows:
- In the initial stages of local edema, it is detected by pressing on the problem area, a hole is formed in it, which disappears for a long time.
- At an advanced stage, swelling is visible to the naked eye.
- Accumulation of fluid in the internal organs can be detected by systematic weighing.
Views of the localEdema:
- Allergic - occurs as a result of the body's reaction to various pathogens, expressed in the form of subcutaneous formations (urticaria, etc.), the larynx is less often affected, causing suffocation.
- Swelling due to venous stasis.
- Lymphatic congestion is the cause of the most dangerous edema. Initially, it is mild, but if treatment is not started on time, elephantiasis may develop.
General edema is formed with a large amount of sodium and water ions in the body and is divided into the following types:
- cordial;
- hypoproteinemic;
- renal;
- fluid congestion in the lungs;
- cerebral edema.
Composition
For the most complete answer to the question of what tissue fluid is, it is necessary to consider its chemical composition:
- water;
- dissolved sugar, s alt, amino acids, enzymes, etc.;
- oxygen;
- carbon dioxide;
- residual effects of cells.
Tissue fluid contains very little protein - only 1.5 grams per 100 milliliters.
Function
What is the function of tissue fluid? It is a connecting element between body cells and blood vessels. The tissue fluid is located directly around the cells, ensuring the timely dissolution of the membranes. Cells that come into contact with tissue fluid receive from it all the necessary elements for nutrition and oxygen. At the same time, processed substances are returnedback into the circulatory system and continue to circulate throughout the body. What is tissue fluid? First of all, it is the most important element that acts as a link in the process of life support of the whole organism.
