Which is the thick layer in arteries for strength?

Arteries have three layers, and the thick, strong middle layer is the muscular wall, called the tunica media. This layer is rich in smooth muscle and elastic fibers, allowing the artery to contract or relax to regulate blood flow and withstand the high pressure of blood being pumped from the heart. The lumen is the hollow passage through which blood flows, homeostasis is the body’s balance process, and pathogens are disease-causing organisms—none of these form the thick, strength-providing wall.
