The epiglottis cartilage moves in response to the act of swallowing, and during swallowing the epiglottis cartilage covers the trachea, allowing food and water to pass smoothly into the esophagus. The epiglottis cartilage is an important part of the larynx and is located above the entrance to the larynx, behind and below the base of the tongue, and is the dividing line between the pharynx and the larynx. The role of the epiglottis cartilage is that the epiglottis structure covers the laryngeal opening during swallowing, preventing food or water from entering the trachea and causing choking or choking. In the absence of swallowing, the epiglottis is open, allowing for smooth breathing and speech. If epiglottis disease occurs, such as epiglottitis, epiglottis cysts, epiglottis tumors, etc., swallowing disorders can occur, and in severe cases, dyspnea may occur, even leading to choking. The epiglottis cartilage plays an important role in swallowing. When suffering from epiglottis disease, you should go to the hospital for examination and treatment in time to avoid adverse consequences.
