Which Respiratory Structure is Distal to the Trachea and Proximal

Question

Which respiratory structure is distal to the trachea and proximal to the alveoli?
A) Pharynx
B) Larynx
C) Bronchus
D) Glottis

Accepted Answer

The bronchus is the structure that is distal to the trachea, meaning it comes after the trachea in the respiratory pathway, and proximal to the alveoli, which are the small air sacs in the lungs where gas exchange occurs. The pharynx and larynx are both higher up in the respiratory pathway, while the glottis is simply the opening between the vocal cords in the larynx.
