Under normal circumstances, once the renal artery enters through the hilum, it splits into two main branches, which each then split into numerous smaller arteries, which deliver blood to different areas of the kidneys, known as nephrons.here are two blood vessels leading off from the abdominal aorta that go to the kidneys. The renal artery is one of these two blood vessels.
Each kidney is reddish-brown, bean shaped organ and is about 4 inches long and 2 inches wide. It has a medial concave surface and a lateral convex surface. On the medial concave border of each kidney, there is a vertical slit called hilum, which is bounded by thick lips of the renal substance.Inside the kidney, the hilum extends into a large cavity called renal sinus.All structures that enter or exit the kidney pass through the hilum. From front backwards, these structures are: 1  Renal vein. 2  Two branches of renal artery. 3  Ureter. 4  Third branch of renal artery. 5  Lymph vessels.nside the kidney, the hilum extends into a large cavity called renal sinus.
