*Protects the trachea in [[Deglutition|Swallowing]], preventing aspiration of foreign material

The larynx 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]]. Closure of the glottis also prevents food passing down the larynx. The relfex stimulation of the mucosa promotes the coughing reflex.

The larynx also allows the passage of air to the lungs and increases the intra-abdominal pressure. The glottis can widen by adduction of the vocal folds when breathing is vigorous. In addition to this, the larynx is used for vocalisation.
