  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.
