Stomach - Stomach wall produces gastric juice which contain hydrochloric acid and protease enzyme

Physical digestion - peristalsis of stomach wall churns and breaks up food particles

Hydrochloric acid- provide optimum pH for protease - kills bacteria and other harmful organism

Chemical Digestion - proteins --> polypeptides

Small Intestine (duodenum)

Intestinal juice - produced by small intestine - contains protease, lipase and amylase

Pancreatic juice- produced by the pancreas- contains protease, amylase and lipase

Bile- produced in the liver- stored in gall bladder - released into small intestine (duodenum) - Bile emulsifies fat (breaks up large fat droplets into smaller fat droplets)- this results in a larger surface area to volume ratio, which speed up digestion by lipase

Digestion is completed in the small intestines (duodenum) Maltose --> Glucose Polypeptides --> Amino acidsLipids --> Fatty acids + Glycerol
