Fun facts: • 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.
