      That would depend on the person and how much exercise they do, the heart pumps about 55-80 ml of blood with each beat for adults and around 25-85 ml per beat for children. For example if an adult who had a resting heart rate of 75 beats per minute (can range from 60-100 beats per minute) and pumps let’s say 70 ml of blood per beat and they don’t exercise at all so the heart rate is constant all day the answer is (beats per minute x how much blood the heart pumps per beat x number of hours in a day x number of minutes in an hour) 75x70x24x60=7,560,000 ml=7,560 liters
