The heart continuously pumps blood through the body and the rate of pumping blood and the volume of blood pumped depend upon the number of beats per minute and the volume flowing through the heart per minute. According to the information, the resting heart beat rate is 72 beats per minute. Further, each beat flows 70 ml of blood through the heart. Thus, the total volume of the blood flowing through the heart per minute at rest will be given by:
Total volume flowing per minute = number of beats/minute * volume of blood flowing/beat
Total volume flowing per minute = 72*70 = 5040 ml/minute
