NEET PG DENTAL EXAM

Detailed explanation-1: -After passage through the esophagus, the bolus will enter the stomach and undergo mechanical and chemical digestion. Mechanical digestion in the stomach occurs via peristaltic contractions of the smooth muscle from the fundus towards the contracted pylorus, termed propulsion.

Detailed explanation-2: -The chemical digestion of proteins begins in your stomach. Carbohydrate and lipid digestion continues in the stomach (lipids are the chemical components of fat). Your stomach releases gastric juices that begin to break down all of the food you’ve eaten.

Detailed explanation-3: -In the large intestine, mechanical digestion begins when chyme moves from the ileum into the cecum, an activity regulated by the ileocecal sphincter. Right after you eat, peristalsis in the ileum forces chyme into the cecum.
