Which component is the middle layer of artery walls?

Explanation:
Artery walls have three layers, and the middle one is the tunica media. This layer is made mainly of smooth muscle cells and elastic fibers, which lets arteries constrict or dilate to regulate blood flow and pressure. In arteries, the tunica media is thickest, giving them the strength to handle the high pressure of pumped blood. The other options aren’t structural layers: an aneurysm is a bulging due to weakness, capillaries lack a tunica media, and neurogenic shock is a physiological condition, not a vessel-wall layer.
