Respiratory Pathway Inhaled air: 1. Enters the nostrils 2. Circulates in the nasal cavity 3. Passes through the pharynx 4. Enters and passes through the larynx to the 5. Trachea 6. Then the trachea bifurcates into 7. Two primary bronchi attached to the 8. Lungs 9. The Bronchi continue to divide until 10. They dead end at the alveolus. i n o u t

Spirographic Record and Vital Capacity Tidal volume is quiet breathing: You are doing it now! Vital Capacity is breathing during a sprint
