*Protects the trachea in [[Deglutition|Swallowing]], preventing aspiration of foreign material
*Protects the trachea in [[Deglutition|Swallowing]], preventing aspiration of foreign material
**During [[Deglutition|swallowing]] the larynx is moved rostrally causing the [[Epiglottis|epiglottis]] to partially cover the laryngeal entrance
**Solid foods are carried over the laryngeal entrance by the muscles of the [[Pharynx - Anatomy & Physiology|pharynx]]
**Fluids are deflected by the [[Epiglottis|epiglottis]]
**Clsure of the glottis also prevents food passing down the larynx
*Relfex stimulation of the mucosa promotes the coughing reflex
*Communication
*Communication
*Increases intra-abdominal pressure
*Increases intra-abdominal pressure
*Vocalisation
*The glottis can widen by adduction of the vocal folds when breathing is vigorous
