Question

How heart works and how many time he beats? In one day?

Answer 1

Explanation:

At an average rate of 80 times a minute, the heart beats about 115,000 times in one day or 42 million times in a year. During an average lifetime, the human heart will beat more than 3 billion times -- pumping an amount of blood that equals about 1 million barrels.

Answer 2

Answer:

The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where it picks up oxygen and gets rid of carbon dioxide. The left side of your heart receives oxygen-rich blood from your lungs and pumps it through your arteries to the rest of your body.

If you use an average of 80 beats per minute, your heart beats about 4,800 times per hour. That's a whopping 115,200 times per day.
