Nitric Oxide
Sympathetic stimulation causes vasoconstriction of most arterioles in the body, except for arterioles in skeletal muscle and the heart where it causes vasodilation.
Nitric oxide is the primary molecule responsible for vasodilation and reducing vascular resistance. It works by relaxing the smooth muscle cells in the blood vessels, leading to increased blood flow and decreased blood pressure. Some medications, such as nitroglycerin, work by promoting the release of nitric oxide to achieve these effects.
Vasodilation in the skin and viscera results from the relaxation of smooth muscle cells in blood vessels. This relaxation causes the blood vessels to widen, increasing blood flow to the skin and internal organs. Vasodilation helps regulate body temperature and can occur in response to various stimuli like heat, exercise, or injury.
The term is vasodilators. These drugs work by relaxing the smooth muscles in blood vessels, which leads to an increase in blood flow and a decrease in blood pressure.
