1st phase- Bolus(chewed, moistened and lubricated by saliva), is moved to the pharynx from the upper surface of the tongue. This is done voluntarily.
2nd phase- contractions of thee pharyngeal walls is what enables food to move through the pharynx. Elevation of the soft palate prevents food from entering into the nose. Elevation of the larynx and epiglottis prevents food from entering into the air passages. Communications with the cavity of the mouth is prevented by the base of the tongue.
3rd phase- Passing of the fod from the esophagus to the stomach.
The 2nd and 3rd phases are involuntary.
