The epiglottis is a flap made of elastic cartilage covered with a mucous membrane , attached to the entrance of the larynx . It projects obliquely upwards behind the tongue and the hyoid bone , pointing dorsally. It stands open during breathing, allowing air into the larynx. During swallowing , it closes to prevent aspiration , forcing the swallowed liquids or food to go down the esophagus instead. It is thus the valve that diverts passage to either the trachea or the esophagus.
The epiglottis is a leaf-shaped flap of cartilage located behind the tongue, at the top of the larynx, or voice box. The main function of the epiglottis is to seal off the windpipe during eating, so that food is not accidentally inhaled. The epiglottis also helps with some aspects of sound production in certain languages.
The epiglottis is a flexible flap at the superior end of the larynx in the throat. It acts as a switch between the larynx and the esophagus to permit air to enter the airway to the lungs and food to pass into the gastrointestinal tract. The epiglottis also protects the body from choking on food that would normally obstruct the airway.
