Which term describes rapid constriction of the blood vessels to decrease blood flow to the area?

Explanation:
Rapid constriction of the blood vessels to decrease blood flow to the area is vasoconstriction. It happens when the smooth muscle in the vessel walls contracts, typically in arterioles, narrowing the lumen and raising vascular resistance. As a result, less blood can reach the tissue, lowering local perfusion. Vasodilation would do the opposite by widening vessels to increase flow. Plasma is simply the liquid component of blood, not a process that narrows vessels.
