Detailed explanation-1: -Chemical digestion is facilitated by the churning action of the stomach caused by contraction and relaxation of smooth muscles. The partially digested food and gastric juice mixture is called chyme. Gastric emptying occurs within two to six hours after a meal.
Detailed explanation-2: -Chyme is a semiliquid mass of partially digested food that also contains gastric juices secreted by cells in the stomach. Cells in the stomach also secrete hydrochloric acid and the enzyme pepsin, that chemically breaks down protein into smaller molecules.
Detailed explanation-3: -That’s where chemical digestion comes in. Chemical digestion breaks down different nutrients, such as proteins, carbohydrates, and fats, into even smaller parts: Fats break down into fatty acids and monoglycerides. Nucleic acids break down into nucleotides.
