Kidney

How the Kidney Works

The kidneys are a pair of reddish-brown organs located on either side of the spine just below the diaphragm, behind the liver and stomach. They are bean-shaped and about 4 and 1/2 inches long, 2 and 1/2 inches wide and one inch thick. The primary function of the kidneys is to remove waste from the body through the production of urine. They also help to regulate blood pressure, blood volume and the chemical (electrolyte) composition of the blood.
