For the most part, the spleen is a silent organ. It performs many functions, some of which few understand or recognize until something happens. When the spleen malfunctions and becomes enlarged due to a condition called splenomegaly, an affected person might start to understand how this organ fits into the grand design. Splenomegaly can be a condition on its own or a symptom of something more serious.
The spleen is a multifunctional organ, located in the upper left abdomen, in a region known as the peritoneal cavity. It is the largest organ in the lymphatic system, which helps the body to fight infections. The organ is both a storage facility for white blood cells and platelets and a filter for red blood cells. Its quality control filtration mechanism narrows the passage in a way that allows only healthy red cells to pass through.
