IMMUNOLOGY

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: -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.

Detailed explanation-3: -The spleen stores blood and when a person loses a lot of blood, for example in a bad car accident, the spleen can respond by releasing blood back into your blood system. The healthy adult spleen weighs around 200g. However, it can become significantly larger when a person is unwell.

Detailed explanation-4: -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.
