What is the function of the epiglottis?

The primary function of the epiglottis is to prevent food and liquids from entering the trachea during swallowing. It is a flap-like structure located at the base of the tongue that folds down over the larynx when you swallow, effectively directing food and liquids into the esophagus. This action is crucial for protecting the air passage, ensuring that the respiratory tract remains clear and allowing for safe swallowing. The epiglottis plays a vital role in the body’s airway protection mechanism, which is essential in preventing choking and aspiration pneumonia.
