Now, the renal cortex is the uppermost section if we don't consider the capsule. And it also contains several important structures of the nephron. So it basically contains something called the Bowman's capsule and the glomerolus. It also contains the proximal and the distal convoluted tubules. And we'll see what that is in just a moment. Now, if we move to right below the renal cortex, we have a section known as the renal medulla.
