    Answer: vasoconstriction

    Explanation: Blood vessels - the more muscular arteries - are often the source of resistance. an artery can actively resist blood flow is by contracting the smooth muscle in its wall, causing the artery to constrict. When an artery constricts, we call it vasoconstriction. During vasoconstriction, the artery gets smaller and offers increased resistance. This causes a decreased blood flow through its lumen, or hollow center. If, on the other hand, the smooth muscle in the wall of the artery relaxes, the blood vessel moves into a state of vasodilation, and its lumen dilates, or gets bigger. This offers decreased resistance and causes an increased blood flow.
