These two accessory organs produce secretion that enter the duodenum. Besides its several other metabolic function, the liver secrets a brownish-green fluid called bile. It contains a mixture of salts such as sodium glycocholate and taurocholate.
Bile is stored in the gall bladder, and is passed into the duodenum through the bile duct. It is is not a digestive enzyme, but emulsifies fats, that is breaks them down into small droplets.
This forms a milky diode called emulsion, and this process is an aspect of mechanical digestion. This increases the surface area for lipase (enzyme that hydrolyses lipids). To act upon the droplets.
The pancreas, besides its function as an exocrine, hormone-secreting gland, secrets pancreatic juices(or fluid) which contains digestive enzymes. Through the pancreatic duct, this fluid passes from the pancreas to meet with the bile from the bile duct, into the duodenum.
