Vasodilation is the widening of your blood vessels. Web vasodilation refers to the widening of the arteries and large blood vessels. Web vasodilators are medications that open (dilate) blood vessels.

A decrease in the size on the lumen of a blood vessel caused by contraction of the smooth muscle in the wall of the vessel.
Web as vasodilation occurs in selected vessels, resistance drops and more blood rushes into the organs they supply. The vasodilation causes a decrease in systemic vascular resistance (svr) and an increase in blood flow, resulting in a reduction of blood pressure. It results from relaxation of smooth muscle cells within the vessel walls, in particular in the large veins, large arteries, and smaller arterioles. Substances that cause vasodilation are called vasodilators. Web vasodilation widening of blood vessels smooth m. (the word dilatation is also sometimes used instead of dilation when talking about a hollow, tubular structure.) vasodilation causes increased blood flow through the blood vessels and decreased blood pressure. Web what is vasodilation? They affect the muscles in the walls of the arteries and veins, preventing the muscles from tightening and the walls from narrowing. Web vasodilation, also known as vasorelaxation, is the widening of blood vessels. The heart doesn't have to pump as hard, reducing blood pressure. A decrease in the size on the lumen of a blood vessel caused by contraction of the smooth muscle in the wall of the vessel.
