Which of these pairs contains the two determinants of mean arterial pressure
A)stroke volume and compliance of vessel walls
B)heart rate and stroke volume
C)heart rate and end-diastolic volume
D)cardiac output and total peripheral resistance

Question

Quizplus · Accepted Answer

Mean arterial pressure (MAP) is determined by both cardiac output (CO) and total peripheral resistance (TPR) according to the formula MAP = CO x TPR. Therefore, choice D is the correct pair as it contains both determinants of MAP. The other choices only include one determinant of MAP or a factor that indirectly affects MAP.
