MICROANATOMY

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

Detailed explanation-3: -The epiglottis is a leaf-shaped flap in the throat that prevents food and water from entering the trachea and the lungs. It stays open during breathing, allowing air into the larynx.
