Which statement about arterial muscle is true?

Explanation:
Arteries have a thick muscular middle layer, the tunica media, rich in smooth muscle. This enables them to constrict or dilate to regulate blood pressure and distribute blood flow as needed. Veins, on the other hand, have thinner walls with less smooth muscle and rely more on valves and surrounding muscle to move blood back to the heart. Because of the thicker, more muscular wall, arterial musculature is more prominent.
