Stomach
It is made up of mucus, enzyme, and hydrochloric acid
Gastric Juice
Stops the action of salivary amylase by denaturing it.

Provides acidic medium for peptic activity.
Kills microbes
Functions of Gastric Juice
It enters the duodenum of the small intestine
Chyme
It contains pancreatic amylase, lipase, and trypsin
Pancreatic Juice
It contains maltase, lipase, and peptidase
Intestinal Juice
It is produced by the liver and is stored in the gallbladder
It helps in emulsifying fats
Bile
It digests emulsified fats and will become fatty acids and glycerol
Lipase
They are digested into polypeptides by trypsin
Protein
They are digested into amino acids by peptidase
Polypeptides
End products of protein digestion
Amino acids
