The Human Heart - Facts About the Heart

You probably think you know what the heart looks like. But you may be wrong. The heart does not look very much like the shapes people draw on Valentine's Day. And it certainly isn't flat, like a paper valentine. A real, live heart is shaped something like an ice-cream cone, with a pointed bottom and a rounded top, like two scoops of ice cream. It is hollow and can fill up with blood. An adult's heart is about the size of a large orange. It weights a little less than a pound.

The heart is in the middle of the chest. It fits snugly between the two lungs. But the heart is tipped over, so that there is a little more of it on the left side than on the right. The pointed tip at the bottom of the heart touches the front wall of the chest. Every time the heart beats, it goes 'thump' against the chest wall. You can feel the thumps if you press there with your hand. You can hear them with your ear.
