Question

Quizplus · Accepted Answer

Peripheral resistance is the resistance to blood flow in the peripheral arteries. When peripheral resistance increases, the heart must work harder to pump blood through the system. This causes blood pressure to rise until it overcomes the resistance. Therefore, blood pressure must rise until it overcomes peripheral resistance.
