− | *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. |

− | *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. |
