Which structure is a passageway for both air and food, connecting the nasal cavity to the larynx and esophagus?

• A. Pharynx
• B. Larynx
• C. Trachea
• D. Alveoli

Answer: (A)

The pharynx serves as a shared passageway for air and food. It sits behind the nasal and oral cavities and channels air toward the larynx and trachea while directing swallowed material into the esophagus. During swallowing, the oropharynx and laryngopharynx handle both air and food, with the epiglottis helping protect the airway by covering the laryngeal inlet. The larynx focuses on routing air and producing sound and is not a conduit for food to the esophagus, the trachea carries air to the lungs, and the alveoli are involved in gas exchange. So, the structure connecting the nasal cavity to both the larynx and esophagus is the pharynx.
