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 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-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.
