Explanation:
Detailed explanation-1: -A small flap of tissue called the epiglottis (eh-pih-GLAH-tus) protects the larynx. When we swallow, the epiglottis covers the larynx to prevent food and liquid from going into the lungs.
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: -Next, the epiglottis, a small but important flap of tissue, folds over the voice box at the top of the windpipe. This keeps food from going down the wrong way.
