Detailed explanation-1: -Your larynx is open at the top so air can move through it to your trachea. When you swallow, however, your epiglottis moves to cover the top of your larynx. Like a roadblock, your epiglottis prevents traffic (food and fluid) from using a specific road (your larynx) and moves traffic to another road (your esophagus).

Detailed explanation-2: -The epiglottis is flap of cartilage located in the throat behind the tongue and in front of the larynx. The epiglottis is usually upright at rest allowing air to pass into the larynx and lungs.

Detailed explanation-3: -No, epiglottis is not a part of the oesophagus.

Detailed explanation-4: -Anatomy of the larynx. The three parts of the larynx are the supraglottis (including the epiglottis), the glottis (including the vocal cords), and the subglottis.

Detailed explanation-5: -The epiglottis drops downward to prevent food from entering the larynx and trachea in order to direct the food into the esophagus. Peristaltic movements propel the food from the pharynx into the esophagus.
