Question

Vasodilation refers to the widening of blood vessels. It results from relaxation of smooth muscle cells within the vessel walls, in particular in the large veins (called venodilators), large arteries, and smaller arterioles. The process is the opposite ofvasoconstriction, which is the narrowing of blood vessels.
