The biliary tract is the system of organs and ducts that are involved in the production, storage, and transportation of bile, a digestive fluid produced by the liver. It includes the liver, gallbladder, and bile ducts. Research in the biliary tract typically focuses on disorders such as gallstones, cholangitis, and biliary obstruction, as well as the development of new diagnostic and treatment approaches for these conditions. This area of research is important in understanding the functioning of the digestive system and in improving the diagnosis and management of biliary tract disorders.
