Web18 jul. 2024 · Vasoconstriction is the narrowing or even closing of the lumen of a vein, artery, or arteriole as a result of smooth muscle cell constriction in the blood vessel wall. By reducing the diameter of a blood vessel, circulating blood must move through a smaller area under higher pressures. Vasoconstriction is regulated by the autonomic nervous system. sick anime charactersWebDaphnia magna heartbeat is myogenic-originating within the animal's heart.
