Question

Quizplus · Accepted Answer

The tunica media is the middle layer of the walls of arteries and veins, composed primarily of smooth muscle cells. Its contraction and relaxation help in the regulation of blood pressure and flow. In the context of veins, while the primary mechanism for moving blood back to the heart involves the action of skeletal muscles and valves within the veins, the tunica media's smooth muscle can influence venous return by changing the vessel's diameter, thus playing a role in the management of venous insufficiency.
