What are the three regions of a renal tubule?

proximal convoluted tubule (red: found in the renal cortex) loop of Henle (blue: mostly in the medulla) distal convoluted tubule (purple: found in the renal cortex) collecting tubule (black: in the medulla)

What is the normal renal cortex measurement?

The normal adult kidney measures approximately 13 cm in length and 4-6 cm in width. The thickness of the renal cortex can be 12 mm. The renal pelvis measures about 4 cm in length.

What is the inner layer of the kidney?

What is the internal anatomy of the kidney?

Kidney Anatomy Internal. The kidney is composed of an inner medulla and an outer cortex surrounded by a tough fibrous capsule. The medulla is composed of a series of conical masses called the renal pyramids. The apex of these pyramids form a papilla which projects into the lumen of the minor calyces.

What is the function of the cortex in the kidney?

The cortex contains mostly nephrons, which are the basic functional units of the kidneys, as well as blood vessels. A number of renal tubules can also be found here. The cortex essentially acts as an anchor for many of the different passageways in the kidney that enable to organ to function.
