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: -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.
Detailed explanation-3: -After breaking down the red blood cells, the spleen stores useful leftover products, such as iron. Eventually, it returns them to the bone marrow to make hemoglobin, the iron-containing part of blood. The spleen also stores blood cells that the body can use in an emergency, such as severe blood loss.
Detailed explanation-4: -The spleen also stores red blood cells, platelets, and infection-fighting white blood cells.
