Answer: I
 The mixture of mucus, HCl, and pepsinogen make up the gastric juice in the stomach. This mixture starts the process of breaking down proteins in food.

Answer: J
 Chyme is a mixture of gastric fluid and food particles in the stomach. It is the end product of the mechanical and chemical digestion that occurs in the stomach before passing into the small intestine.
