Question

Quizplus · Accepted Answer

Elastic arteries have a well-developed tunica media with elastic fibers throughout, providing elasticity needed for blood pressure regulation. In contrast, muscular arteries have a thicker layer of smooth muscle in the tunica media, which allows them to contract and regulate blood flow to specific organs or regions of the body.
