What does the epiglottis do during swallowing?

The epiglottis plays a crucial role in directing food and liquids during the swallowing process. Its primary function is to cover the windpipe, or trachea, when you swallow. This action is essential because it prevents food or liquid from entering the airway, which could lead to choking or aspiration into the lungs. By closing over the trachea, the epiglottis helps ensure that the swallowed substances are channeled into the esophagus, the tube leading to the stomach. This protective mechanism is vital for safe swallowing and proper respiration.
