The correct path taken by inhaled air after it leaves the larynx is
Correct answer: C. trachea, bronchi, bronchioles, alveoli
- A. trachea, alveoli, bronchi, bronchioles
- B. bronchi, trachea, bronchioles, alveoli
- C. trachea, bronchi, bronchioles, alveoli
- D. bronchioles, bronchi, trachea, alveoli
Explanation
Air passes down the single trachea, which divides into two bronchi, one to each lung, and these branch repeatedly into ever finer bronchioles ending in the alveolar sacs where exchange occurs. The sequence runs from wide and few to narrow and numerous, which is the quick way to check any order given in an option. Cartilage supports the trachea and bronchi but disappears in the smallest bronchioles.

About Human Respiratory System
The human respiratory system conducts air to the alveoli, where oxygen and carbon dioxide exchange occurs across thin respiratory surfaces. Questions cover the nasal passage, trachea, bronchi, lungs, diaphragm and intercostal muscles, ventilation mechanics and gas transport, while distinguishing breathing and gaseous exchange from cellular respiration.
