Relax (Your Blood Vessels), And Lower Your Cholesterol The chemical, nitric oxide, signals blood vessels to open and close in response to the body's changing need for increased or decreased blood flow. Individuals with elevated cholesterol have an impaired ability to relax, or dilate, their blood vessels, which researchers attribute to a problem in nitric oxide activation. In individuals whose cholesterol levels were lowered by the drug fluvastatin, more nitric oxide was produced, improving dilation.

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. 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 ex

Thread: why does alcohol dilate blood vessels? Simply the heart, a big muscle, is connected to a series of tubes, the arteries and the veins, which carry blood to the various parts of the body. Arteries carry the blood away from the heart, while veins bring blood back to the heart. The arteries are connected to the veins via very small vessels called capillaries. Electrical and chemical signals to the heart cause it to pump the blood into the arteries. Further, a number factors can cause the blood vessels to expand (dilate) or contract. In doing so they can increase or decrease the amount of effort the heart needs to put forth to deliver the blood.
