Detailed explanation-1: -The spleen is a small organ inside your left rib cage, just above the stomach. It’s part of the lymphatic system (which is part of the immune system). The spleen stores and filters blood and makes white blood cells that protect you from infection.
Detailed explanation-2: -It serves as a graveyard for old or flawed red blood cells (oxygen-carrying cells) and as a storage site for blood and platelets (essential for clotting). The spleen also clears bacteria and is important for proper immune function, especially in fighting bacteria.
Detailed explanation-3: -About 25% to 30% of red blood cells (RBCs) are stored in the spleen, along with about 25% of platelets normally sequestered in the spleen.
Detailed explanation-4: -The spleen helps keep harmful microorganisms out of the bloodstream. It holds key components of the body’s immune system. The spleen also removes unhealthy, old, and misshapen red blood cells from circulation. Red blood cells carry oxygen throughout the body and remove carbon dioxide (a waste product).
Detailed explanation-5: -The spleen filters your blood and also stores your red blood cells, platelets, and white blood cells. But if your spleen is removed, other parts of the lymphatic system can take over these functions. The spleen is part of your body’s lymphatic system.
Detailed explanation-6: -The spleen controls the level of white blood cells, red blood cells and platelets (small cells that form blood clots). It screens the blood and removes any old or damaged red blood cells. If the spleen doesn’t work properly, it may start to remove healthy blood cells.
