Vasodilation or dilation of the blood vessels is due to a decrease in vascular resistance. As a result of the dilation of blood vessels, blood flow increases. Mammals or warm blooded creatures use vasodilation to move warm blood closer to the surface of the skin where heat can be released. Vasodilation serves as a form of cooling in warm blooded animals.
