Quizplus · Accepted Answer

The tunica media is the middle layer of blood vessels and contains vascular smooth muscle, which helps regulate the vessel diameter and blood flow. It is found in arteries, arterioles, and veins, but not in capillaries. The tunica adventitia is the outermost layer, and the tunica intima is the innermost layer. The tunica media is thicker in arteries than in veins, and helps to maintain arterial blood pressure.
