How many times does the human heart beat in a lifetime?
On average the heart beats 3 billion times during a person's life. This means that it beats about 100,000 times in one day and about 35 million times in a year.
Some Quick Heart Facts:
- If you squeeze a tennis ball hard you are actually using the same amount of force that your heart uses to pump the blood through your body.
- In the human body there are about 5.6 liters of blood. All of this blood circulates through the body three times a minute.
