A small flap of tissue that closes the windpipe when you swallow food to keep you from choking?

The small flap of tissue that closes the windpipe during swallowing is called the epiglottis. It acts as a protective mechanism, preventing food and liquids from entering the trachea and directing them towards the esophagus instead. This helps to ensure that the airway remains clear and reduces the risk of choking. The epiglottis plays a crucial role in the swallowing process, functioning automatically as we eat or drink.
