Detailed explanation-1: -The spleen acts as a filter. It weeds out old and damaged cells and helps control the amount of blood and blood cells that circulate in the body. The spleen also helps get rid of germs. It contains white blood cells called lymphocytes and macrophages.
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.
Detailed explanation-3: -The spleen helps keep harmful microorganisms out of the bloodstream. It holds key components of the body’s immune system.
