The biliary tract, also known as the biliary system or bile duct system, is an essential component of the digestive system in the human body. It consists of a series of ducts and structures that facilitate bile production, storage, and transportation. The liver produces bile. It is essential for the digestion and absorption of fats and fat-soluble vitamins. The biliary tract includes the liver, where bile is produced; the gallbladder, where bile is stored and concentrated; and a network of ducts. These include the hepatic, cystic, and common bile duct. These ducts in the biliary tract carry bile from the liver to the gallbladder. In the gallbladder, the bile is stored and released to the small intestine after eating a meal. The biliary tract also intersects with the pancreatic duct, allowing digestive enzymes from the pancreas to mix with bile. Proper functioning of the biliary tract is vital for digestion, and disorders in this system, such as gallstones, inflammation, or cancers, can lead to significant health issues.
