Lymphatic System

The lymphatic brass is a vital part of the insubordinate body, along with the thymus, bone marrow, spleen, tonsils, appendix, and Peyers patches in the small intestine.
The lymphatic system is a network of lymph nodes connected by lymphatic vessels. This system transports lymph by dint ofout the body.
Lymph is regulateed from precarious that seeps through the thin walls of capillaries into the bodys tissues. This fluid contains oxygen, proteins, and other nutrients that nourish the tissues. Some of this fluid reenters the capillaries and some of it enters the lymphatic vessels (becoming lymph). Small lymphatic vessels connect to larger ones and eventually form the thoracic duct. The thoracic duct is the largest lymphatic vessel. It joins with the subclavian venous blood line vessel and thus returns lymph to the bloodstream. The fluid also transports unusual substances ( such as bacteria), crabmeat cells, and dead or damaged cells that may be largess in tissues into the lymphatic vessels. Lymph also contains many white blood cells.




All substances transported by the lymph pass through at to the lowest degree one lymph node, where foreign substances target be filtered out and unmake before fluid is returned to the bloodstream. In the lymph nodes, white blood cells can collect, interact with each other and antigens, and generate immune responses to foreign substances. Lymph nodes contain a mesh of tissue that is tightly jam-packed with B cells, T cells, dendritic cells, and macrophages. Harmful microorganisms ar filtered through the mesh, then identified and attacked by B cells and T cells.
Lymph nodes are often clustered in areas where the lymphatic vessels branch off, such as the neck, armpits, and groin.If you want to get a full essay, smart set it on our website: Orderessay
