Final answer:
Air passes through various structures including the pharynx, larynx, trachea, and bronchi during inhalation in the respiratory system.
Explanation:
The correct sequence of structures through which air passes during inhalation is:
- Pharynx
- Larynx
- Trachea
- Bronchi
Air passes through the nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles, terminal and respiratory bronchioles, alveolar ducts, and alveolar sacs in the lungs for gas exchange with capillaries.
The respiratory system has defenses like mucus production in the lungs and cilia in the bronchi and bronchioles that protect against foreign materials entering the system.
