If cardiac output increases,the peripheral resistance must _____ for arterial blood pressure to remain constant.

Question

Quizplus · Accepted Answer

If cardiac output increases, to maintain constant arterial blood pressure, the peripheral resistance must decrease. This is due to the fact that an increase in cardiac output causes an increase in blood flow, and if the peripheral resistance remains constant, it would result in a significant increase in blood pressure. Therefore, increasing the diameter of the blood vessels through vasodilation reduces the peripheral resistance, balancing out the increase in cardiac output and maintaining constant arterial blood pressure.
