Been reading on here about the liver and bile as in when it is made recently. Thought it would be of interest to read this extract from netdoctor.co.uk
"Bile is the thick, greenish fluid, secreted continuously by the liver cells at the rate of up to one litre per day. It is stored and concentrated in the gall bladder and plays an important role in our digestive system in breaking down dietary fat.
Within the liver, the bile passes along tubes or ducts to the gall bladder.
When food, especially fat, leaves the stomach, the gall bladder is stimulated to contract and bile passes along the common bile duct to the first part of the small bowel (duodenum) along with secretions from the pancreas.
In primary biliary cirrhosis, there is a reduction in the number of bile ducts, leading to interference with bile flow."
