Lymph, spleen
| Question | Answer |
|---|---|
| Functions of the spleen | Defense, Tissue repair, Hematopoiesis, Red blood cell destruction/Platelet destruction |
| Functions of the spleen 2 | Blood reservoir, helps restore blood to the circulatory system if needed, holds about 350ml, very vascular organ. |
| Lymphatic Vessels | Collect fluids that drain from tissues of the body (lymph) and return back to the blood |
| Lymphatic capillaries | Transport lymph to larger lymphatic vessels, Collect tissue fluid that forms lymph |
| Lymphatic ducts | Collect lymph from the network of lymphatic vessels and drain it back into the blood circulation |
| Lymphoid organs | Hematopoiesis immunity (WBCs) also filters body fluids |
| Lymph nodes | Filtration of lymph before it enters the bloodstream, Mechanical filtration removes particles |
| Aggregated lymph nodules | Immunity at common points of entry for pathogenic microbes (think Tonsils) |
| Thymus | Hematopoiesis – site of T cell development also produces hormone thymosin that regulates T cell development |
| Spleen | Tissue repair, destruction of old RBCs, Bood reservoir, blood filtration, Hematopoiesis immunity (WBCs) |
