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 liver plays an active role in the process of digestion through the production of bile. Bile is a mixture of water, bile salts, cholesterol, and the pigment bilirubin. Hepatocytes in the liver produce bile, which then passes through the bile ducts to be stored in the gallbladder.he liver performs many essential functions related to digestion, metabolism, immunity, and the storage of nutrients within the body. These functions make the liver a vital organ without which the tissues of the body would quickly die from lack of energy and nutrients.
