the chewing motion (mastication) triggers the brain to believe that a meal is being ingested. This stimulates the parasympathetic vagus nerve to fire impulses to the stomach to release digestive juices in anticipation for the meal. This also causes duodenal juices to be secreted, and the fundus (entrance area) of the stomach to dilate/relax in anticipation of the entry of a food bolus.
