Facts About Your Heart!!!– When you’re exercising, it takes your blood about ten seconds to get from your heart to your big toe and back. In fact, a kid’s heart has to push blood through about 60,000 miles (96,560 kilometers) of blood vessels—that’s long enough to circle the Earth two and a half times! – All that pumping takes a lot of effort. To push blood, an average heart beats a hundred thousand times a day. That means that in a lifetime, the average human heart will beat more than two and a half billion times. – The heart is about the size of your fist. (When you were a baby it was the size of your baby fist). – The heart is a muscle, just like the other muscles in your body!! It weighs about a pound, or less than half a kilogram. – The heart pumps thousands of liters of blood through your body every day. Blood is pumped out of the heart in two directions. First it sends blood without any oxygen to the lungs to get oxygen. It then pumps the blood containing oxygen around all the other parts of the body. After delivering its oxygen, the blood returns to the heart to start the process of getting oxygen all over again.
