Occurs mechanical digestion by teeth and chemical digestion of starch by amylase

The end of mastication is food bolus swallowed to be digested in stomach

contains amylase and liquid for lubricate food and make small pieces stick together

Transfer food from the mouth to stomach by peristaltic

The first part of small intestines that receives pancreatic juices

Enzyme in the epithelial lining carry out chemical digestion of maltose and peptides

Has villi and extremely large surface area to absorb of digested food molecule

Secret pancreatic into duodenum through duct for chemical digestion of protein, fats, starch

Protease : Trypsin : break down protein ( peptides to amino acid

Produces Insulin hormone to regulate blood sugar levels (decrease the blood sugar level)

Produces Sodium Carbonates (a base) to neutralize stomach acids as chyme enters the duodenum.

Liver produces bile, a fluid loaded with lipids and salts to emulsify fats

Gallbladder stores bile, breaks up the globs of fat into smaller droplets,

Absorb water from undigested food and absorb bile salts to pass back to the liver
