PATHOLOGY

Detailed explanation-1: -Vasodilation is the widening of blood vessels as a result of the relaxation of the blood vessel’s muscular walls.

Detailed explanation-2: -Vasodilation occurs naturally in response to low oxygen levels or increases in body temperature. Its purpose is to increase blood flow and oxygen delivery to parts of the body that need it most. In certain circumstances, vasodilation can have a beneficial effect on a person’s health.

Detailed explanation-3: -Vasodilation occurs naturally in your body in response to triggers such as low oxygen levels, a decrease in available nutrients, and increases in temperature. It causes the widening of your blood vessels, which in turn increases blood flow and lowers blood pressure.

Detailed explanation-4: -When the muscle layer of a blood vessel relaxes, the blood vessel diameter becomes larger. This is called “vasodilation". Vasodilation lowers the blood pressure.

Detailed explanation-5: -The tunica media is the layer of an artery which is responsible for vasoconstriction and vasodilation. Within this layer the vessel wall is smooth muscle.
