Your heart is located in the upper left-hand side of your chest and if you place your hand there, you can feel it beating. The heart continually pumps blood to all parts of the body, and never stops beating, even when you are asleep. Because of its importance, many complex surgeries (and even artificial hearts) have been developed to keep one's heart going thump, thump, thump.

Wow! During your lifetime, your heart will beat 2 1/2 billion times without stopping to rest. This site provides information about what the human heart is, and how it grows and develops. It also explains the structure of the heart, with images and diagrams. There are activities for the classroom, index cards, images, and links to additional reading about the heart. "Like a pumping machine, the heart provides the power needed for life. This life-sustaining power has, throughout time, caused an air of mystery to surround the heart."

"Did you give your friends valentines and little heart-shaped candies on Valentine's Day? Do you ever cross your heart when making a promise that you really, really mean? Or turn on the radio to hear a guy singing about his broken heart?" KidsHealth explains that your heart isn't your emotional center and doesn't make you fall in love. The heart is a tireless muscle pumping blood to your organs. And without it, your other organs wouldn't get the oxygen or energy they need to do their job.
