Subsequently, one may also ask, what does the cortex of the kidney contain?

It contains the renal corpuscles and the renal tubules except for parts of the loop of Henle which descend into the renal medulla. It also contains blood vessels and cortical collecting ducts. The renal cortex is the part of the kidney where ultrafiltration occurs. Erythropoietin is produced in the renal cortex.

Likewise, what is the function of the renal artery? Arteries are numerous in your body. They are blood vessels that are responsible for (with a couple of exceptions) carrying oxygenated blood through the body. Your renal artery, then, is a blood vessel that carries oxygenated blood to your kidneys.

Also asked, what is the blood flow through the kidney?

Blood flows into your kidney through the renal artery. This large blood vessel branches into smaller and smaller blood vessels until the blood reaches the nephrons. In the nephron, your blood is filtered by the tiny blood vessels of the glomeruli and then flows out of your kidney through the renal vein.
