Explanation Arteries are divided into three classes by size and they are- Conducting arteries are the biggest arteries. They only serve to supply blood at high speed to the main "exit ramps" heading off to each organ. Examples of conducting arteries are the common carotid and subclavic arteries, aorta, pulmonary artery, and common iliac arteries. The tunica media consists of 40 to 70 layers of elastic sheets, perforated like a slice of cheese rolled into a tube, alternating with thin layers of smooth muscle, elastic fibers, and collagen. The elastic tissue dominates the view in histological sections. Distributing arteries are smaller branches that distribute blood to different bodies, such as exit ramps and state highways serving individual cities...
