Detailed explanation-1: -Arteries contain smooth muscle cells, which contract and relax to change the diameter of blood vessels, controlling blood flow to ensure that cells get the correct amount of oxygen and nutrients.
Detailed explanation-2: -These results demonstrate that in isolation, an abnormality in the regulation of vascular smooth muscle contraction produces a change in blood pressure, and therefore, an isolated increase in vascular smooth muscle tone will produce hypertension.
Detailed explanation-3: -The prime function of the arterial smooth muscle cell (SMC) in adult individuals is to contract and relax, thereby regulating blood flow to target tissues.
Detailed explanation-4: -Arterioles, small blood vessels that carry blood away from your heart, are connectors between your arteries and capillaries. They control your blood pressure and blood flow throughout your body, using their muscles to change their diameter.
