  - - - Pharynx - Trachea - Oesophagus
  - - - Bronchus - Alveoli
  - - - Trachea - Right lung (three lobes) - Left lung (two lobes)
- - - - Air enters - Intercostal muscles contract - Diaphragm flattens
    - - Air leaves - Intercostal muscles relax - Diaphragm relaxes
  - - - CO2 leaves the blood and enters the alveolus while O2 leaves the alveolus and is collected by the red blood cells in blood
        
        Blood leaves the lungs with a high concentration of oxygen to distribute throughout the body
