Welcome to the kidney page, a branch of the biomedical engineering page.
Most people have two kidneys, located on either side of the spine, just below the rib cage.
The kidneys maintain the proper chemical balance in the body. They filter out waste products and extra fluid and eliminate them from the body through the urine. The kidneys also help control blood pressure and the production of red blood cells. The process of filtering the bodies wastes and preparing urine is detailed in the pictures and captions below. Blood is pumped from the heart through large blood vessels to the kidneys.
