The epiglottis is a small, leaf-shaped flap of cartilage located at the top of the larynx (voice box). Its primary function is to prevent food and liquid from entering the trachea (windpipe) during swallowing.
Here's how it works:
* During swallowing: The epiglottis folds down over the opening of the trachea, effectively blocking it off.
* During breathing: The epiglottis remains upright, allowing air to pass freely into the lungs.
