Welcome to the Wonderful World of the Heart

When you picture your heart, I bet you see a heart like the ones on Valentine cards. The heart actually looks like an up-side down pear and is about the size of your clenched fist. Did you know that the heart is a muscle? That's right, just like the ones in your arms and legs. This powerful pear-shaped muscle pumps about 4300 gallons of blood per day. That's like 4300 full gallons of milk! Wow! To pump this 4300 gallons of blood per day your heart has to beat(expand and contrast) 100,000 times a day. For an average 70 year lifetime your heart would beat around 2.5 billion times.
