Explanation:
The air travels through the bronchi from the trachea, and then to the bronchioles and then eventually reaches the alveoli for exchange of gases with blood. The respiratory route of air in the respiratory tract is: Nostrils → nasal cavity →Pharynx → Larynx →Trachea → Bronchi → Bronchioles → Alveoli or air sacs.
