Physiology and Pathophysiology of the Biliary Tract: The.
Clonorchis and 0pisthrochis infection can lead to the development of carcinoma of the biliary tract. Ascaris lumbricoides,a more common cosmopolitan parasite, occasionally obstructs the biliary tree, resulting in acute cholangitis(16).Echinococcal disease can cause biliary obstruction due to mass effect.The biliary tract is functionally integrated with the digestive tract by neurohormonal mechanisms in the fasting and digestive phases. The liver secretes bile continuously into the intrahepatic ducts flowing into the extrahepatic ducts.The biliary tract, (biliary tree or biliary system) refers to the liver, gall bladder and bile ducts, and how they work together to make, store and secrete bile. Bile consists of water, electrolytes, bile acids, cholesterol, phospholipids and conjugated bilirubin.

These bile pigments give stool its typical color.
Biliary system Biliary tract; Bile tract Information The biliary system creates, moves, stores, and releases bile into the duodenum. This helps the body digest food. It also assists in transporting waste products from the liver to the duodenum.
