The renal arteries carry a large portion of total blood flow to the kidneys.

Up to a third of total cardiac output can pass through the renal arteries to be filtered by the kidneys.

Instead of entering the kidney at the hilus, they usually pierce the upper or lower part of the organ.

[9] Renal artery stenosis, or narrowing of one or both renal arteries will lead to hypertension as the affected kidneys release renin to increase blood pressure to preserve perfusion to the kidneys.
