Epiglottis
|
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 of tissue that covers the tracheal opening during swallowing to prevent food from entering the lungs.
Detailed explanation-3: -Epiglottis is a flap of cartilage behind the root of the tongue, which is depressed during swallowing to cover the opening of the windpipe.
Detailed explanation-4: -The correct option is C. Epiglottis. The upper opening of the windpipe is guarded by a muscular flap called epiglottis. The epiglottis closes the windpipe at the time of swallowing food.
