Every day our heart pumps and pumps blood around our body. And our blood Carries oxygen around to every organ and muscle, even our brain. In fact, without our heart pumping, we would not survive very long at all. And it is easy to forget how much work our little heart is putting in.
Your system of blood vessels and arteries all combined is over 60,000 miles long, that is long enough to go around the world more than twice! Actually, your heart is located in the center of your chest between your lungs, a common misconception is that is located to the left. The little thump thump sound of the heartbeat is the sound created by four valves of your heart closing and opening.
As a kid, your hear beat will most likely average at around 90 to 120 beats per minute and as you get older this will get slower to about 60 to 72 beats per minute. And the incredible thing is that during just one day these beats can generate enough energy to drive a truck over 20 miles (32 km).
If you were to add this all together in a whole lifetime that would be the equivalent of driving to the moon and back. Imagine that in your lifetime your heart generates enough energy to travel over 238,900 miles. If you want to learn how hard a heart works when pumping you can simply grab a tennis ball and squeeze it as tight as you can. That is exactly how hard a heart works to pump blood.
Your heart actually works twice as hard as any muscle in your body, which is why it needs a much richer blood supply. And if you were wondering, your heart problems weights in the realm of 8 to 10 ounces!
