Answer 2

While vasodilation is the widening of your blood vessels, vasoconstriction is the narrowing of blood vessels. It's due to a contraction of muscles in the blood vessels. When vasoconstriction occurs, the blood flow to some of your body's tissues becomes restricted. Your blood pressure also rises.
