Explanation:
Detailed explanation-1: -The epiglottis is a small, movable “lid” just above the larynx that prevents food and drink from entering the windpipe.
Detailed explanation-2: -The epiglottis is usually upright at rest allowing air to pass into the larynx and lungs. 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.
Detailed explanation-3: -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.
