Vedclass · Answer

(A) The $Epiglottis$ is a thin,cartilaginous flap located at the entrance of the larynx (voice box).During the act of swallowing,the $Epiglottis$ acts as a lid to cover the glottis (the opening of the windpipe or trachea).This prevents food particles from entering the respiratory tract.If the $Epiglottis$ fails to close properly during swallowing,food particles may enter the trachea,triggering a cough reflex to expel the foreign material and protect the airway.
