Question

Quizplus · Accepted Answer

Vasoconstriction and vasodilation are processes that involve the smooth muscle of arteries to control the size of the arterial lumen, or opening. When the diameter in the arteries is smaller, the blood pressure is higher. This can either be a desired effect when we need to increase our blood pressure to deliver more blood at a faster rate, or it can be due to other things like drugs or stress causing the smooth muscle to contract, causing vasoconstriction. Vasodilation occurs when the vessels are not constricted, and blood pressure is lowered.
