- Our nose cleans and warms up the air.
- The air passes through the larynx and the windpipe.
- Then the windpipe is divided into the two bronchial tubes.
- Finally the air goes into the lungs.
The air goes the opposite direction from the lungs to the nose/mouth through the bronchial tubes, the windpipe and the larynx.
