What is Lymphatic System definition/concept

The lymphatic system is an important part of the circulatory system . It is formed by ganglia, lymphoid organs and a network of ducts that connect these structures to each other, as well as with the general circulation known as lymphatic vessels.

This system is located throughout the body, except for the central nervous system, and is also directly related to the body’s immune system or defense system.

Lymphatic circulation

The lymphatic system intervenes in the processes of collecting fluids and various substances that are deposited or stored in tissues, as well as in the transport of immune system cells to the places where they are required.

The drainage function of the lymphatic system allows fluid accumulated in the tissues resulting from the inflammatory response, trauma, infectious process or venous insufficiency to be taken back to the venous circulation to be filtered by the kidney and finally eliminated by the urine. Lymphatic System

The fluid contained within the lymphatic system is known as lymph, it has a yellowish color similar to blood plasma, it is composed of water, proteins and immune system cells such as lymphocytes, which are a type of white blood cell.

lymphatic structures

Lymph nodes . Along the path of the lymph vessels is located a series of nodules known as lymph nodes. These constitute a kind of filter and tend to be distributed forming groups that are located mainly at the level of the neck, armpits, groin and inside the abdomen along the great vessels, such as the aorta and the vena cava. In the lymph nodes, the recognition of microorganisms such as viruses and bacteria is performed, initiating the activation of B lymphocytes, which are a type of white blood cell responsible for the production of antibodies; for this reason the lymph nodes enlarge when an infection occurs. Lymphatic System

Tonsils . The lymphatic tissue is located at strategic points in the digestive system, in the oral cavity, it is found at the beginning of the pharynx, in structures known as tonsils and adenoids; there is also lymphatic tissue in the appendix, this strategic location allows for a defense tissue at two important points of entry of germs into the body, such as the airway and the mouth.

Timo . In the embryonic stage and during childhood, there is great immunological activity in the thymus, an organ located behind the sternum, which is related to the maturation of T lymphocytes, which are a type of white blood cell responsible for recognizing body cells and for differentiating foreign cells, as well as for coordinating the response of the defense system against microorganisms. Lymphatic System

Spleen . It is an organ located inside the abdomen and on the left side, its main function is to eliminate aging blood cells and also act as a reservoir or reservoir for blood. The spleen also plays an important role as a lymphatic organ, acts as a filter that collects the various antigens (substances foreign to the body) being able to produce immunoglobulins and substances necessary for the cells of the defense system to eliminate the bacteria that are protected by a capsule, as in the case of pneumococcus, bacteria that cause diseases such as pneumonia.
