What Do You Mean by Vasodilation

Vasodilation—the widening of blood vessels—increases blood flow in a region. In tissue that is ischemic, vasodilation can be induced to enhance the effects of radiotherapy by increasing the delivery of oxygen and blood to the target.

What is called vasodilation?

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.

What is the function of vasodilation?

The purpose of vasodilation is to increase blood flow to the tissues in the body. In response to a need for oxygen or nutrients, tissues can release endogenous vasodilators. The result is a decrease in vascular resistance and an increase in capillary perfusion.
