The heart, about the size of the human fist, pumps about five liters of blood through 60,000 miles of blood vessels each minute at rest. Since the average adult body contains about five liters of blood, nearly all of it passes through the heart each minute. The resting heart rate of most untrained humans is 60 to 80 beats per minute, and 55 to 75 milliliters of blood is pumped out of the heart with each beat (defined as the stroke volume).

About one thirteenth or 7.5 percent of your body weight is blood. a 13 stone man has about 14 pounds or 4 litres of blood surging around his body. When the body is resting the adult human heart pumps out about 4 litres of blood per minute, this rises to 27 litres per minute under vigorous exercise. This adds up to a grand total of more than 32 million litres of blood pumped in a seventy year life.

The heart pumps about 55-80 ml (1/3 cup) of blood with each beat for adults and around 25-85 ml per beat for children. An adult heart pumps about 6,000-7,500 liters (1,500-2,000 gallons) of blood daily. The average adult body contains about five quarts of blood which continually circulates throughout the body. The shortest trip to the heart muscles takes only a few seconds. The trip to the toes takes over a minute.
The average heartbeat is 72 times per minute. In the course of one day it beats over 100,000 times. In one year the heart beats almost 38 million times, and by the time you are 70 years old, on average, it beats 2.5 billion times.
So 72 beats per minute x 55 to 80 ml per pump would be between about 4 to 6 liters per minute.
