Study Notes
Phases of Deglutition
- The glottis is closed during the pharyngeal phase of deglutition as a protective reflex.
- The tongue elevates upward and backward during the oral phase to push the bolus from the mouth to the pharynx.
- The pharyngeal phase of deglutition involves protective reflexes to direct food to the esophagus and protect the respiratory system.
- The main function of the pharyngeal stage (second phase of deglutition) is to ensure the safe passage of food into the esophagus.
