Now recall that our kidney is divided into two regions. The outer portion of the kidney is known as the renal cortex, while the inner portion of the kidney is known as the renal medulla. And this dashed line basically separates the cortex from the medulla region in our kidney. So we see that the nephron actually encompasses both the cortex and the medulla of our kidney is found in the cortex as well as in aramidoula. So let's begin with our initial point on the nephron, which is found in the cortex. Now recall that the renal artery brings the blood to our kidney.
