The epiglottis is a thin, flexible flap of tissue that is located at the base of the tongue and covers the opening of the windpipe during swallowing. It is a crucial part of our respiratory and digestive systems, acting as a protective barrier to prevent food, liquids, and other foreign substances from entering our lungs. The epiglottis works in coordination with the larynx and vocal cords to ensure that food and liquids are directed to the esophagus and stomach during the act of swallowing. Dysfunction of the epiglottis can result in a variety of respiratory and digestive problems, making its proper function essential for optimal health.
