Which statement best describes the epiglottis?

Which statement best describes the epiglottis?

• A. Keeps food from entering the airway during swallowing
• B. Filters incoming air
• C. Produces vocal sounds
• D. Transports air to the lungs

Answer: (A)

The epiglottis primarily serves to protect the airway during swallowing. When you swallow, the larynx rises and the epiglottis bends downward to cover the opening to the trachea, directing food and liquid toward the esophagus and away from the lungs. This prevents aspiration and choking. Filtering air is done by the nasal passages and airway lining, not by the epiglottis. Producing vocal sounds involves the vocal cords in the larynx, and transporting air is the job of the entire airway system from the trachea onward.
