Question

What structure prevents food and drink from entering the trachea; conducts air and produces sound?
A) the esophagus
B) the bronchi
C) the pharynx
D) the nasal cavity
E) the larynx

Accepted Answer

The larynx is commonly known as the "voice box" and is responsible for conducting air and producing sound. It also contains the epiglottis, a flap of tissue that prevents food and drink from entering the trachea. The esophagus is responsible for transporting food and drink to the stomach. The bronchi are the two main branches of the trachea that lead to the lungs. The pharynx is a passageway for both air and food/drink, and connects the nasal cavity and mouth to the esophagus and trachea. The nasal cavity warms, moistens, and filters air as it enters the respiratory system.
