So how much blood does your heart pump?
Cardiac Output: The amount of blood your heart pumps in one minute. Stoke volume: The amount of blood your heart pumps in one beat.

Mouse and Elephant A mouse's heart beats about 700 times per minute and an elephant's about 30. A mouse lives less than three years, an elephant more than 60. What's the connection?

Is there a relationship between size of the animal and its heart rate?

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.
