Differences in blood flow to an organ are related to the resistance to flow in the arterioles that supply that organ.

Question

Quizplus · Accepted Answer

Blood flow to an organ is determined by the resistance to flow in the arterioles that supply that organ. If the arterioles have high resistance due to constriction, blood flow will be reduced, whereas if the arterioles have low resistance due to dilation, blood flow will increase. Thus, differences in blood flow to organs can be directly related to changes in resistance in the arterioles supplying them.
