  2. Origin: [L. vas a vessel + dilator.]


  1. Vasodilation

    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, large arteries, and smaller arterioles. In essence, the process is the opposite of vasoconstriction, which is the narrowing of blood vessels. When blood vessels dilate, the flow of blood is increased due to a decrease in vascular resistance. Therefore, dilation of arterial blood vessels decreases blood pressure. The response may be intrinsic or extrinsic. In addition, the response may be localized to a specific organ, or it may be systemic. Drugs that cause vasodilation are termed vasodilators.
