The respiratory system


Inhalation: To breathe in.

Exhalation: To breathe out.









Inhalation:

  1. Our nose cleans and warms up the air. 
  2. The air passes through the larynx and the windpipe
  3. Then the windpipe is divided into the two bronchial tubes
  4. Finally the air goes into the lungs.

Exhalation:

The air goes the opposite direction from the lungs to the nose/mouth through the bronchial tubes, the windpipe and the larynx.
