Renal blood vessels. Angiogram (X-ray) of blood vessels in a healthy kidney. The large artery entering the kidney is the renal artery, which branches into many smaller capillaries inside the kidney. The capillaries form the core of glomeruli, units within the kidney that filter waste products from the blood. The waste products leave the kidney as urine.
