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: -Study findings indicate that glottal closure constitutes the major mechanism of prevention of aspiration during the intra-and postdeglutitive periods of swallowing and that laryngeal elevation may also have a significant role in protecting the airway during the intradeglutitive period.

Detailed explanation-3: -Composed mostly of elastic cartilage, the epiglottis joins the external ear and the auditory tube of the middle ear in utilizing the structural support and flexibility this type of connective tissue imparts.

Detailed explanation-4: -How does my epiglottis move to cover my larynx? Healthcare providers believe several things happen to move your epiglottis into place when you swallow: Your larynx and hyoid bone-the bone in the middle of your throat-move up and forward, causing the back of your tongue to put pressure on your epiglottis.

Detailed explanation-5: -The epiglottis is a triangular-shaped, elastic cartilage that helps to protect the airway during swallowing. The tip of the triangle points rostrally and in a normal horse, the epiglottis sits dorsal to the soft palate during breathing.
