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: -What is vasodilation? Vasodilation is the medical term for when blood vessels in your body widen, allowing more blood to flow through them and lowering your blood pressure. This is a normal process that happens in your body without you even realizing it.

Detailed explanation-3: -The widening of blood vessels is called vasodilation, while the narrowing of blood vessels is called vasoconstriction.

Detailed explanation-4: -Vasodilation is the widening of your blood vessels. It happens when smooth muscles found in the walls of arteries or large veins relax, allowing the blood vessels to become more open. This leads to an increase in blood flow through your blood vessels as well as a decrease in blood pressure.

Detailed explanation-5: -As the total cross-sectional area of the vessels increases, the velocity of flow decreases. Blood flow is slowest in the capillaries, which allows time for exchange of gases and nutrients. Resistance is a force that opposes the flow of a fluid. In blood vessels, most of the resistance is due to vessel diameter.
