Choke is a(n) _______ obstruction.

• A. Esophageal
• B. Tracheal
• C. Nasal
• D. Laryngeal

Answer: (A)

Choking describes an obstruction of the airway—the path air takes to reach the lungs. The trachea is the main airway after the throat, so when a foreign object or piece of food gets stuck there, airflow is blocked and you experience choking. The esophagus is the swallowing tube to the stomach; a blockage there causes trouble swallowing rather than an immediate inability to breathe. Nasal obstruction blocks the nose but doesn’t create the sudden airway blockage characteristic of choking. Obstruction at the larynx can impede breathing as well, but choking most directly refers to a blockage of the trachea.
