I have no idea, thats why im asking the question!!
Well, I've just calculated 720, 000, based on an Olympic swimming pool holding 2500,000 litres (Wikipedia); and one heartbeat pumping 70cm3 of blood at 70 beats/minute, and an average lifetime being 70 years
= 1.8 x 10^11/2.5 x 10^6
= 720000
Because the heart works to pump blood throughout our body. No blood, no life. Your heart stops working, our brain, which allows us to do everything we do, would die along with the rest of our body which is entirely dependent on the brain. The brain being quite dependent on how the heart beats, having it beat properly.
the heart is a muscle, and every muscle needs blood because the blood caries oxygen to the cells of that muscle which is then converted into energy and this is what makes our bodies work. your heart however is a special muscle that pumps your blood to all of the muscles in your body.
so that we can take in oxygen and breathe out carbon dioxideso we can breathe so we can live.
If your valves are not working then your blood will flow in the wrong direction
it pumps out blood to the rest of your body which your body needs to live. if your heart stopped, you would die! And you take in oxygen which also helps you
