A Tale of Teamwork
by Inna, Steph, Nat, and Kylan
You can find your heart and lungs inside of your chest.
Your heart and lungs work together to help you breathe air.
The blood in your body travels in and out of your heart and lungs to get oxygen. This will help give your body energy.
There are four chambers in a heart; two atriums on top and two ventricles on the bottom.
The right side of the heart is smaller than the left side.
