The smallest of the arteries eventually branch into arterioles. They, in turn, branch into a extremely large number of the smallest diameter vessels—the capillaries. Next blood exits the capillaries and begins its return to the heart via the venules.

Capillaries have the thinnest walls and also the smallest diameters because their function is to exchange materials.
