Arteries or veins

Question

Explain whether the arteries or veins comprises of more muscle tissue? How the walls of these two types of blood vessels are different?

Answer 1

The walls of the arterial system have thicker muscles as in arteries the blood circulates under the higher pressure. Veins are more flaccid as compared to the arteries. From lumen to external layer both types of vessels are made up of the muscle tissue, endothelium, and connective tissue. In both, endothelium is the single layer of cells. Within the arteries, portion of the muscle tissue is thicker rather than in veins and in these vessels external connective tissue is thicker as compared to that in the arteries. Arteries are pulsating blood vessels. The arterial pulse may be felt in the medical examination, example, through the palpation of radial artery in internal and lateral face of wrist near to the base of the thumb.
