PATHOLOGY

Detailed explanation-1: -When a person swallows the epiglottis folds backward to cover the entrance of the larynx so food and liquid do not enter the windpipe and lungs. After swallowing the epiglottis returns to its original upright position.

Detailed explanation-2: -A flap of tissue called the epiglottis sits over the top of the trachea. This flap blocks food and drink from going down into the trachea when you swallow.

Detailed explanation-3: -A cartilaginous flap called epiglottis specifically prevents the entry of food into the glottis (opening of the windpipe) during swallowing.
