Your Lungs
Your lungs are spongy bag-like organs in the chest, used for breathing. They are part of the body’s RESPIRATORY system. All animals that have a backbone and breathe have lungs. When you breathe in, air filled with oxygen flows into the lungs. When you breathe out, the lungs empty.

Your lungs are protected by the ribs in your chest. When you are physically active, your lungs work harder to supply the additional oxygen your muscles need.
Just like regular exercise makes your muscles stronger, it also makes your lungs stronger!
What you need:
Step by step:
Step 1: Cut out two pieces of pink paper and glue them to your cardboard.
Step 2:
Draw on the airway branches of your lungs , like branches of a tree. Sellotape together two bendy straws.
Step 3: Sellotape a small bag onto each end of the straws. Tape straws onto cardboard. Blow into the straws to see the lungs come to life!
