Epiglottis – a flap of skin in the throat
The epiglottis is a thin flap of cartilage at the back of the mouth that covers the entrance to the larynx during swallowing.
A pea got (epiglottis) into a flap (flap) when he got stuck in the throat.
The function of the epiglottis is to prevent food and drink from falling down the airway. Without the epiglottis we would not be able to swallow without drowning in whatever we are drinking.
The epiglottis allows food being swallowed to pass into the esophagus and therefore into the digestive system. This function is automatic because of the swallowing reflex.
