Learning Objectives. By the end of this section, you will be able to: Compare and contrast the three tunics that make up the walls of most blood vessels. Distinguish between elastic arteries, muscular arteries, and arterioles on the basis of structure, location, and function.
Arterioles control blood flow into capillaries and create the highest resistance in the circulatory system. Arterioles have one or two layers of smooth muscle cells. Capillaries contain a single layer of endothelial cells and the occasional pericyte.

Blood Vessel Structure. The structure of the blood vessels is designed for the ebb and flow of blood as its pumped through the body. Both arteries and veins (not capillaries) are made up of several layers or tunics. The innermost layer is called the tunica interna.
