Question

Quizplus · Accepted Answer

The tunica media is responsible for maintaining blood pressure and continuous blood circulation. It is made up of smooth muscle fibers and can contract or relax to regulate blood flow and pressure. The tunica intima is the innermost layer of the artery and is composed of endothelial cells, basement membrane, and a thin layer of connective tissue. The basement membrane and tunica externa (also known as tunica adventitia) are involved in supporting and protecting the artery rather than regulating blood pressure.
