Spleen
The spleen, an organ of the lymphatic system, varies in shape and size. It is located in the upper left of the abdominal cavity, in contact with the diaphragm. The spleen removes debris from the blood and breaks down aged red blood cells. A part of the broken-down red blood cell is converted into bilirubin and transported to the liver. The spleen can also act as a blood reservoir with a volume of 350 milliliters.
