Explanation The cardiovascular system comprises of five general classes of blood vessels, which are as follows: 1. Arteries: It carries oxygenated blood away from the heart to the body tissues. It is categorized as muscular and elastic arteries. Muscular arteries: They are the medium-sized arteries that distribute blood to the skeletal muscles and internal organs of the body. They possess thick tunica media with a higher percentage of smooth muscle fibers. The luminal diameter and thickness are about 4 mm and 1 mm, respectively. Elastic arteries: These arteries are resilient, elastic vessels that are capable of stretching and recoiling as per the change in the heartbeat and the arterial pressure. The average luminal diameter is 1.5 cm and wall thickness is 1 mm. 2. Arterioles: They are the smallest branches of the arteries that move the blood into the capillaries. The arterioles have poorly defined tunica externa and the tunica media possess scattered smooth muscle fibers that might not form a complete layer. The luminal diameter is 30 µm and the wall thickness is 6 µm...
