Liver:
Produces bile which is responsible for the emulsification of fats (separates fats globules to enhance lipase activity)
Bile produced in the liver is commonly stored in the gall bladder until a release
Pancreas:
Secretes bicarbonate ions into the duodenum to neutralize stomach acids (intestine pH is usually ~ 7 – 8)
Also secretes lipase (for fat digestion), amylase (for carbohydrate digestion) and protease (for protein digestion)
Pancreatic proteases are activated by enzymes and not by acid conditions (enterokinase converts trypsinogen to trypsin)
