Detailed explanation-1: -Vasodilation is the widening of blood vessels as a result of the relaxation of the blood vessel’s muscular walls. Vasodilation is a mechanism to enhance blood flow to areas of the body that are lacking oxygen and/or nutrients.
Detailed explanation-2: -Blood vessels also contain muscle, and that muscle controls just how wide or narrow your blood vessels are at any given time. When blood vessels get wider, that’s vasodilation. The opposite process, when blood vessels constrict and get narrower, is called vasoconstriction.
Detailed explanation-3: -Definition. Vasoconstriction is the narrowing or even closing of the lumen of a vein, artery, or arteriole as a result of smooth muscle cell constriction in the blood vessel wall. By reducing the diameter of a blood vessel, circulating blood must move through a smaller area under higher pressures.
