Lymphoid tissue

Lymphoid tissue (synonym lymphatic tissue) is a General term used to refer to structures in which there is a formation of lymphocytes. Lymphoid tissue person is about 1% of body weight and is one of the most important components of lymphoid organs. These include the lymph nodes (see Lymphatic system), spleen (see), the thymus gland (see), the tonsils (see). In the mucosa of the digestive tract lymphoid tissue presents single and collected into groups (Peyer's patches) lymph follicles, especially a large number of them available in the walls of the Appendix. Parts of lymphoid tissue are found in the mucous membrane of certain bodies (bronchi, the urinary tract and kidneys).
One of the main functions of lymphoid organs is their participation in the processes of blood (limfopoez). Lymphocytes (see) capable, ameboid moving through the vascular wall and phagocytose and give rise to different types of cellular forms, including plasma cells (see connective tissue)that participate in the formation of antibodies. With this ability of lymphocytes linked important function of lymphoid tissue - participation in its protective reactions of the organism. In chronic inflammatory processes of the centers of lymphoid tissue appear in various organs.
Lymphoid tissue are very sensitive to internal and external influences. Thus, under the influence of x-rays lymphocytes quickly die. With the introduction of thyroid hormones lymphoid tissue grows. Great influence on the development of lymphoid tissue are hormones napochechnikov crust. Insufficient function napochechnikov crust induces the growth of lymphoid tissue. Introduction of adrenal cortex hormones leads to degeneration of lymphoid tissue and death of lymphocytes.
