Quizplus · Accepted Answer

Blood pressure is directly dependent on both cardiac output (the amount of blood pumped by the heart per minute) and peripheral resistance (the resistance or force the blood encounters as it flows through the blood vessels). Therefore, the best choice is D which includes both factors.
