Quizplus · Accepted Answer

Elastic arteries are the largest arteries in the human body and are characterized by the presence of a high concentration of elastic fibers in the tunica media, which allows them to expand and contract in response to changes in blood pressure. The subclavian artery is considered an elastic artery because it is a large artery that branches directly from the aorta and has a high concentration of elastic fibers in its tunica media. The other arteries listed are muscular arteries, which have a higher concentration of smooth muscle cells in the tunica media than elastic fibers.
