The kidneys are two bean-shaped organs located on either side of the spine, at the small of the back. The kidneys filter wastes from the blood, and the wastes are carried out of the body in urine. Urine flows through tubes (ureters) to the bladder, where it is stored until a person is ready to urinate. The waste and urine then leave the bladder to exit the body through a tube called the urethra.
