Structure of a kidney - image description

The diagram shows a side view of a kidney with the adrenal gland sitting on top of it. It shows the ureter (a tube that carries urine to the bladder) leaving the kidney and also two blood vessels joining the kidney. These are the renal artery, which carries blood to the kidney, and the renal vein, which takes blood away from the kidney.  

In the diagram, the kidney is shown surrounded by a lightly shaded area representing an envelope of fibrous tissue called Gerota’s fascia. It acts as a covering for the kidney to protect it from injury. The diagram shows a three-dimensional view to show a layer of fat underneath the fascia.
