Vasodilation refers to the widening of the blood vessels to facilitate increased blood flow. This usually occur in blood vessels, namely; the arteries, arterioles.

Vasodilation occur by the blood vessels dilating and this leads to a decrease in vascular resistance and the resulting outcome is an increase in cardiac output.
