The kidneys are located in the middle of the back, one on each side of the spinal column. A kidney is roughly the size of a fist, and it contains filters that remove waste from the blood. The kidneys regulate the amount of water within the body. The kidneys also help regulate blood pressure, produce vitamin D and secrete erythropoietin, a hormone that helps in the formation of new red blood cells.

5 facts
