Explanation:
Detailed explanation-1: -Pulse is defined as the alternate expansion and recoil of an artery. With each heartbeat, blood is forced into the arteries causing them to dilate (expand). Then the arteries contract (recoil) as the blood moves further along in the circulatory system.
Detailed explanation-2: -Tunica intima: The inner layer touches your blood and keeps it flowing smoothly through your arteries. Media: The middle layer is elastic, so it expands and contracts to maintain the right blood pressure in your arteries.
