In the lumen ofthe digestive tract,bile salts breakthe lipid dropletsapart by emulsification.

Bile becomes moreconcentrated thelonger it remains inthe gallbladder.
Liver
The liversecretes bilecontinuously—about 1liter per day.
The release of CCK by theduodenum triggers dilationof the hepatopancreaticsphincter and contractionof the gallbladder. This ejectsbile into the duodenumthrough the duodenal ampulla.
