Little kids draw hearts everyday. They always looking like this . . .
But in reality, the heart doesn't actually look like that. The human heart is about the size of a fist. A lot of blood is supplied to the heart. So it looks red like meat. People who are obese, their heart looks yellow because of the fat that surrounds it. 'In school, kids say the Pledge of Allegiance. You would put your hand either on the left or right side of your chest right? Well, actually the heart is in the middle in between your lungs.
The heart pumps blood in and out through your body. Pumping all that blood is a lot of work. The average heart would beat about 100,000 times a day. In a lifetime, the heart would beat more then 2.5 billion times.
Eat healthy and exercise can help the heart do its job.
