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.hroughout each day, the epiglottis spends the vast majority of its time relaxed at the superior edge of the larynx just posterior to the tongue. In this position, air is able to enter the pharynx from the nose or mouth and pass freely into the larynx and onward to the lungs.
Epiglottitis Overview. Epiglottitis is a medical emergency that may result in death if not treated quickly. The epiglottis is a flap of tissue that sits at the base of the tongue that keeps food from going into the trachea, or windpipe, during swallowing.When it gets infected and inflamed, it can obstruct, or close off, the windpipe, which may be fatal unless promptly treated.ith continued inflammation and swelling of the epiglottis, complete blockage of the airway may occur, leading to suffocation and death. Autopsies of people with epiglottitis have shown distortion of the epiglottis and its associated structures including the formation of abscesses (pockets of infection).
