Answer:
The middle layer of the walls of arteries and veins is called the tunica media. It's made of smooth muscle and elastic fibers. This layer is thicker in arteries and thinner in veins.

Explanation:
Arteries and arterioles have thicker walls than veins and venules because they are closer to the heart and receive blood that is surging at a far greater pressure (Figure 2). Each type of vessel has a lumen—a hollow passageway through which blood flows.
