Explanation:
Detailed explanation-1: -Because of the pumping action of the heart, the pressure within the arteries cycles between a higher pressure and a lower pressure. The higher pressure occurs during the contraction of the heart’s left ventricle. The higher pressure is known as the systolic blood pressure.
Detailed explanation-2: -Blood pressure in the arteries is much higher than in the veins, in part due to receiving blood from the heart after contraction, but also due to their contractile capacity. The tunica media of arteries is thickened compared to veins, with smoother muscle fibers and elastic tissue.
