Which of the Following Represents a Correct Air Flow

Question

Which of the following represents a correct air flow?
A) Bronchus to trachea to bronchioles
B) Trachea to bronchioles to alveoli
C) Bronchi to bronchioles to alveoli
D) Nasopharynx to larynx to bronchioles to bronchi

Accepted Answer

Air flows from the bronchi to the bronchioles to the alveoli, as oxygen needs to reach the smallest air sacks in the lungs for proper gas exchange. The trachea is a larger passageway above the bronchi, while the nasopharynx and larynx are part of the upper respiratory system and not involved in air flow to the lungs.
