The laryngopharynx is the lower part of the pharynx, located behind the larynx and extending from the hyoid bone to the esophagus. It serves as a passageway for both air and food, directing air to the trachea and food to the esophagus. This region plays a crucial role in the respiratory and digestive systems. The laryngopharynx is lined with mucous membranes that help protect it from pathogens and facilitate the movement of food and air. It also contains the epiglottis, a flap that prevents food from entering the airway during swallowing.
