What is the function of the epiglottis, a small flap of tissue located at the top of the windpipe?

Explanation

The epiglottis is a small, flexible flap of cartilage located at the top of the windpipe that folds down to cover the airway during swallowing, helping direct food and liquid safely into the esophagus and preventing them from accidentally entering the lungs. This automatic, well-coordinated action happens quickly and largely without conscious effort each time a person swallows. Occasionally, if this reflex is disrupted or timed incorrectly, food or liquid can enter the airway instead, triggering a protective coughing reflex to help clear it.
