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: -These disc-shaped cells are filtered by the spleen based on their physical characteristics. They can only reenter the bloodstream if they’re able to pass through a tiny splenic structure called the interendothelial slit. When the red blood cells’ size, shape, or ability to deform is altered, they can’t pass through.
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: -Another useful purpose of your spleen is storing blood. The blood vessels in human spleens are able to get wider or narrower, depending on your body’s needs. When vessels are expanded, your spleen can actually hold up to a cup of reserve blood.
