1 Immune system - Spleen. 2  Major functions of the spleen include removing abnormal blood cells and making components of the immune system. 3  Since the spleen is involved in so many bodily functions, it is vulnerable to a range of disorders.  Disorders of the spleen include splenomegaly, hypersplenism and splenic rupture.
While the spleen functions chiefly to filter blood, it also stores red blood cells and platelets. In instances where extreme bleeding occurs, red blood cells, platelets, and macrophages are released from the spleen. Macrophages help to reduce inflammation and destroy pathogens or damaged cells in the injured area.
