ANATOMY

Detailed explanation-1: -The flap that covers the trachea during swallowing so that food does not enter the lungs. Anatomy of the larynx. The three parts of the larynx are the supraglottis (including the epiglottis), the glottis (including the vocal cords), and the subglottis.

Detailed explanation-2: -When you swallow, a flap called the epiglottis moves to block the entrance of food particles into your larynx and lungs. The muscles of the larynx pull upward to assist with this movement. They also tightly close during swallowing.

Detailed explanation-3: -Next, the epiglottis, a small but important flap of tissue, folds over the voice box at the top of the windpipe.

Detailed explanation-4: -When you swallow, the aryepiglottic and thyroepiglottic muscles pull down the epiglottis to close the entry to the larynx, preventing anything from entering the trachea.

Detailed explanation-5: -Your epiglottis moves to cover your larynx and trachea (inset) to keep food from going into your larynx and trachea.
