Deglutition also called swallowing is the process in the body which allows a substance to pass through the mouth, to the pharynx, and into the esophagus, while shutting the epiglottis. 

Deglutition is divided into three phases:

  • The buccal phase occurs voluntarily in the mouth.
  • The pharyngeal phase occurs involuntarily when food enters the pharynx.
  • The oesophageal phase occurs involuntarily in the oesophagus.
