In this model, the straws represent your t_ _ _ _ _ _ and bronchial tubes, the balloons represent your l_ _ _ _
The bottle is your c_ _ _ _, and the glove is your d_ _ _ _ _ _ _ _, a sheet of muscles under your chest.

When you breathe out, or exhale, your diaphragm relaxes back up. The space inside your chest gets smaller forcing the air out of your lungs.
