A flap of cartilage which is depressed during swallowing to cover the opening of the windpipe/trachea?

• A. Larynx
• B. Epiglottis
• C. Uvula
• D. Pharynx

Answer: (B)

The epiglottis is the flap of elastic cartilage at the top of the larynx that acts as a lid for the airway during swallowing. When you swallow, the larynx rises and the epiglottis tilts downward to cover the opening of the trachea, preventing food or liquid from entering the windpipe. This protective mechanism is crucial to avoid aspiration. The larynx itself houses the vocal cords and remains involved in airway protection, but the actual covering of the tracheal opening is accomplished by the epiglottis. The uvula, located at the back of the soft palate, helps with swallowing and speech but does not seal the airway. The pharynx is the passageway guiding swallowed material toward the esophagus and is not responsible for closing the tracheal opening.
