The spleen plays important roles in regard to red blood cells (also referred to as erythrocytes) and the immune system. It removes old red blood cells and holds a reserve of blood, which can be valuable in case of hemorrhagic shock, and also recycles iron. In humans, up to a cup (236.5 ml) of red blood cells can be held in the spleen and released in cases of hypovolemia. 2  It can store platelets in case of an emergency and also clears old platelets from the circulation.

However, in abnormal conditions it may give rise to pain felt as an aching sensation deep behind the left ribcage. This area may also hurt when it is touched. This could signal splenic damage, splenic rupture, or splenomegaly. Severe pain arising from the spleen often signals the presence of splenic infarction.
