In less than a minute, the heart can deliver blood to every cell. So, how many times does the human heart beat in a day?
In a day’s time, the human heart will beat about 100,000 times, pumping 2000 gallons of oxygen-rich blood; the path that these blood “walks” in the blood vessels of various tissues and organs of the human body will be as long as 6 Ten thousand kilometers. For a fist-sized heart, this is really a onerous task. Therefore, the heart is not important.
