Detailed explanation-1: -Vasoconstriction is what healthcare providers call it when the muscles around your blood vessels tighten to make the space inside smaller. This is the opposite of vasodilation, which opens your blood vessels to make the space inside bigger.
Detailed explanation-2: -The main cause is atherosclerosis, which is the build-up of fatty deposits that narrow a blood vessel, usually an artery. The narrowed blood vessel reduces the circulation of blood to the associated body part. Peripheral vascular disease mainly affects blood vessels of the legs and kidneys and, less commonly, the arms.
Detailed explanation-3: -Arterioles: Arteries branch into smaller vessels called arterioles. Both arteries and arterioles are very flexible. They get bigger or smaller to help maintain your body’s blood pressure.
