What does my heart do?


Can You Hear My Heart, bip bip, with You !


Your heart is very special muscle which keeps blood moving around your body. If you put your hand on your chest near your heart, you'll feel it beating. Each time it beats, it pumps blood out around your body.
Your body is using up oxygen all the time, keeping you alive, so it has to keep getting more from your lungs.
One side of your heart pumps blood to your lungs to get oxygen. The other side pumps it around your body.
