Bile Duct System and Gallbladder. The bile duct (biliary) system provides the channels through which bile is transported from the liver to the duodenum (through the papilla of Vater). The liver is found in the right upper corner of the abdomen, immediately below the diaphragm. In health it weighs 3-4 pounds.
The gallbladder is the sac-like structure under the liver that stores about 30-50 ml of bile. The liver produces bile, and the gallbladder stores it.From there it is excreted, travels down the bile duct, where it passes through the pancreas, which produces lipase (which does break down fat), before it goes into your small intestine.ile emulsifies the fats, or breaks them into smaller particles, to assist in their digestion. If the bile salts crystallize, you get gallstones. The gallbladder will release bile only under the influence of cholecystokinin.
