MEDICAL PHYSIOLOGY

Detailed explanation-1: -Arteries have thick elastic walls and veins have valves.

Detailed explanation-2: -Arteries play a major role in nourishing organs with blood and nutrients. Arteries are always under high pressure. To accommodate this stress, they have an abundance of elastic tissue and less smooth muscle.

Detailed explanation-3: -Arteries have thick walls and are situated superficially in comparison to other blood vessels. Arteries are blood vessels, the network of pathways through which the oxygenated blood travels away from the heart to various cells, tissues, and organs of the human body.

Detailed explanation-4: -Walls of the arteries are thick because they have to withstand the high pressure released from the heart during the process of pumping the blood. Therefore, the thick walls of the arteries help in maintaining the blood pressure simultaneously by controlling blood flow.

Detailed explanation-5: -In elastic arteries, the tunica media is rich with elastic and connective tissue. The aorta: The aorta makes up most of the elastic arteries in the body.
