Skeletal muscles are the muscles found in your legs and arms and throughout the body. The skeletal system is different from the smooth muscle system in organs like your liver and the cardiac muscle in your heart because the skeletal muscles contract voluntarily.
Vasoconstriction is necessary to increase blood pressure and regulate the flow of blood to the muscles. But vasodilation is necessary for the body to carry away toxins and waste from muscles as the exercise progresses. The vasodilation response also helps regulate blood pressure and keep it from going too high.
