Here's how it works:
* During swallowing: The epiglottis, a small flap of cartilage, folds down to cover the opening of the trachea. This prevents food and liquids from entering the airway and instead directs them into the esophagus, the tube leading to the stomach.
* During breathing: The epiglottis remains open, allowing air to flow freely into the trachea and lungs.
The epiglottis plays a crucial role in protecting the respiratory system from choking hazards.
