Spleen [Lien (Splen), Pna, Bna, Jna, Lnh]

The spleen is one of the most mysterious organs in our body. Although its functions have been known for a long time, only recently have we begun to understand how they are interconnected and why the spleen is so important to our health. In this article we will learn about what the spleen is, what functions it performs, and what diseases can lead to its deficiency. The human lymphatic system is

Introduction The spleen is an unpaired, two-lobed organ of the abdominal cavity and belongs to the organs of the lymphoid system. It is part of the body's immune system. Separation by the blood organ into erythrocytes and leukocytes in our blood completely depends on the secretion of a cell or group of cells - hemocytoblasts, located in the granules of the so-called lymphoid strands or molecular-phagocytic cells called macrophages, the main function of which is to utilize decay products, cleansing the body and identifying destructive elements. The structure of the organ is complex; the spleen tissue consists of blood vessels, lymph nodes, bone marrow and connective tissue.

**Phylogenesis (development of the organism) of the spleen**

An ancient preparation, which clearly belonged to the ventricular department and could articulate with the hepatic duct, disappeared in the evolution of animals as a result of the historical separation of the tooth. The embryo produces a substance homologous to that found in birds, but it is absent in most vertebrates. It connects to the wall of the atrium of the heart, which fuses with the ventricle along its entire length. Determined on the right side of the stomach behind the liver bladder. At the 9th week, almost the entire metacelmia is fused to the brain, connecting to it through secondary nerves. Once destroyed, the adnexes are replaced by new growths, or involutions, connected by remnants and can be connected by anterior medullary neurons. At 23 weeks, a vascular structure is formed in the anterior part of the adnexa, which is shrouded in membranous tissue on the inner side, representing a smooth connective tissue sheath that carries the primary arteries inside. By 24 weeks on the sides di
