In vertebrates, the kidneys are two reddish-brown bean-shaped organs. They are located on the left and right sides of the retroperitoneal space and are about 12 centimetres (4+12 inches) long in adults. They get blood from the paired renal arteries and get blood from the paired renal veins. Each kidney is connected to a ureter, which is a tube that transports excreted urine to the bladder.
