b. An indicator of the tone of the arterial blood vessel walls
c. The average pressure throughout each cycle of the heartbeat
d. The product of the cardiac output and the peripheral vascular resistance
ANS: C
The MAP is the average pressure throughout each cycle of the heartbeat and is significant because it is the pressure that actually pushes the blood through the circulatory system. The difference between the systolic and diastolic pressures describes the pulse pressure. An indicator of the tone of the arterial blood vessel walls describes the pulse pressure. The product of the cardiac output and the peripheral vascular resistance describes the arterial blood pressure.
