The Common Passageway Shared by the Respiratory and Digestive Systems

Question

The common passageway shared by the respiratory and digestive systems is the
A) larynx.
B) glottis.
C) vestibule.
D) pharynx.
E) trachea.

Accepted Answer

The pharynx is the common passageway shared by the respiratory and digestive systems. It connects the nasal and oral cavities to the larynx and esophagus, allowing for air and food to pass through. The other choices (larynx, glottis, vestibule, and trachea) are all structures within the respiratory system, but do not serve as a common passageway with the digestive system.
