1. The main function of the epiglottis is to prevent food and liquids from entering the trachea (windpipe) during swallowing. It acts as a flap that covers the opening of the trachea, directing food and liquids down the esophagus instead.
2. The epiglottis also plays a role in protecting the airway during breathing by closing off the trachea when we swallow, preventing food or liquid from entering the lungs.
3. It helps in producing sound by controlling the flow of air through the vocal cords.
4. The epiglottis also helps in regulating the flow of air into the lungs during breathing by opening and closing the airway as needed.

Functions of the Epiglottis:
1. Prevents Aspiration:
- During swallowing, the epiglottis folds back over the opening of the larynx (glottis) to prevent food and liquid from entering the airway (trachea).
2. Speech:
- The epiglottis helps to modulate speech sounds by altering the resonant qualities of the vocal tract.
3. Laryngeal Protection:
- The epiglottis protects the larynx from entry of foreign objects, excessive secretions, and gastric reflux.
4. Sensory Reflex:
- The epiglottis is innervated by the superior laryngeal nerve, which triggers a reflex cough when stimulated by foreign objects or irritants.
5. Immune Response:
- The epiglottis contains specialized cells that can filter out and destroy pathogens that enter the respiratory system.
