Chewing, in which food is mixed with saliva, begins the mechanical process of digestion. This produces a bolus which can be swallowed down the esophagus to enter the stomach.And stomach is a J shaped organ Here it is mixed with gastric acid until it passes into the duodenum where it is mixed with a number of enzymes produced by the pancreas.
the stomach churns the food by strong peristaltic movement This is physical digestition Food gets properly with gastric juice produced in the stomach The gastric gland start product gastric juice soon as the food enter the stomach Gastric juice contains HCl mucous and inactive protein digestive enzymes called pepesinogen HCl make the food soften Secretion of gastric juice controlled by the sight smell and taste of food
