Detailed explanation-1: -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. After swallowing the epiglottis returns to its original upright position.
Detailed explanation-2: -The epiglottis is a flap made of elastic cartilage tissue covered with a mucous membrane, attached to the entrance of the larynx. It stays open during breathing, allowing air to pass through.
Detailed explanation-3: -The epiglottis is a small, movable “lid” just above the larynx that prevents food and drink from entering the windpipe. Swelling of the epiglottis can completely block the airway.
