Solution

The correct option is B 5040 mL
Cardiac output is the volume of blood being pumped by the heart in a minute. It is equal to the heart rate multiplied by the stroke volume.
During a cardiac cycle, each ventricle pumps out approximately 70 mL of blood. (Stroke volume)

Cardiac output = Stroke volume × Number of beats per minute = 70 mL × 72
= 5040 mL/min
