ANATOMY

Detailed explanation-1: -There are two types of nephrons-cortical nephrons (85 percent), which are deep in the renal cortex, and juxtamedullary nephrons (15 percent), which lie in the renal cortex close to the renal medulla.

Detailed explanation-2: -Medulla is the region of the kidney deep to the cortex and contains the collecting ducts.

Detailed explanation-3: -The correct statement should read: The medulla is deep to the cortex (not the vortex) of the kidney. The kidney is made up of the outermost cortex and the inner medulla which is found inferior or deep to the kidneys’ cortex.

Detailed explanation-4: -The renal medulla is the innermost part of the kidney. The renal medulla is split up into a number of sections, known as the renal pyramids. Blood enters into the kidney via the renal artery, which then splits up to form the segmental arteries which then branch to form interlobar arteries.

Detailed explanation-5: -Hence, the region of the nephron found in the renal medulla is Henle’s loop.
