Detailed explanation-1: -It starts in the esophagus where strong wave-like motions of the smooth muscle move balls of swallowed food to the stomach. There, the food is churned into a liquid mixture called chyme that moves into the small intestine where peristalsis continues.
Detailed explanation-2: -Time to empty: Stomach Food is mixed with gastric juice. Strong muscular contractions in the stomach wall reduce the food to chyme – a thick milky material. The pyloric sphincter at the lower end of the stomach slowly releases chyme into the duodenum. Emptying the stomach takes 2–6 hours.
Detailed explanation-3: -Bolus is food that has been mixed with saliva. Chyme is food that has been mixed with gastric juice. Bolus is chewed and then swallowed to reach the stomach. Chyme enters the small intestine after passing through the stomach.
