Reticuloendothelial system

The reticuloendothelial system (mononuclear phagocyte system) is a set of cells and tissues that perform the functions of phagocytosis, antibody production and immunity.

The reticuloendothelial system includes:

1. Macrophages are cells found in connective tissue, lymph nodes, spleen, liver, lungs, etc. They carry out phagocytosis of foreign particles, microorganisms, and damaged cells.

2. Reticular cells are found in the lymph nodes, spleen, and bone marrow. Perform the function of phagocytosis.

3. Histiocytes - located in connective tissue, perform phagocytosis.

4. Kupffer cells are liver macrophages.

5. Microglia are macrophages of the central nervous system.

6. Endothelial cells of the bone marrow and spleen sinuses.

Thus, the reticuloendothelial system is an important component of the immune system, providing protection to the body from foreign agents and decay products of its own cells.

_Reticulendothelial System_

_Introduction:_ **Reticuliendothelial system** is a system of organs of the growing body that occupies an intermediate position between the system of blood vessels and the system of plasmacytic cells. This analytical center is responsible for the localization of antigens in the blood and their functions. By interacting with lymphocytes, this system controls the processes of induction and combustion. The reticuloendothelial systems created specific receptors for various macrophages.
