7. Fun facts:
The heart pumps about ml (1/3 cup) of blood with each beat for adults and around 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.
