Explanation Arteries are thick-walled blood vessels that carry blood away from the heart. The blood is pumped out from the heart with a pressure which is received by the arteries. The wall of the artery is made up of three layers. Because of its thick wall layers, the lumen of the arteries is narrow. Middle layer which is slightly thicker out of the three layers is made up of smooth muscles and elastic tissues. It is equipped to withstand the high pressure of the blood...
