Question
What structure of the respiratory system provides air and food passage?
A. Esophagus
B. Primary bronchi
C. Pharynx
D. Larynx
Solution
The structure of the respiratory system that provides both air and food passage is C. Pharynx.
Here's why:
-
The pharynx, also known as the throat, is a tube-like structure that connects the nasal and oral cavities to the esophagus and larynx.
-
When we breathe, air enters the body through the nose or mouth and travels down the pharynx, into the larynx, and then into the lungs via the bronchi.
-
When we eat, food enters the body through the mouth and travels down the pharynx and into the esophagus, which leads to the stomach.
-
Therefore, the pharynx serves as a common pathway for both air and food, making it the correct answer to this question.
The other options listed do not serve this dual purpose. The esophagus is involved in food passage but not air passage. The primary bronchi and larynx are involved in air passage but not food passage.
