Biliary tract

Biliary Tract

The biliary tract, also known as the biliary tree, is a system of organs and ducts that participate in the production, storage, and transportation of bile. Bile, a fluid produced by the liver, aids in the digestion of lipids in the small intestine. The biliary tract includes the gallbladder and the bile ducts.

Anatomy[edit | edit source]

The biliary tract consists of the gallbladder and the bile ducts. The bile ducts are classified into two main types: the intrahepatic bile ducts and the extrahepatic bile ducts. The intrahepatic bile ducts are located within the liver, while the extrahepatic bile ducts are located outside the liver.

Function[edit | edit source]

The primary function of the biliary tract is to facilitate the digestion of lipids in the small intestine. This is achieved through the production, storage, and transportation of bile, a fluid that contains bile acids, which are critical for the digestion and absorption of dietary fats.

Diseases[edit | edit source]

Diseases of the biliary tract can lead to severe health problems. These include gallstones, cholangitis, and cancer of the biliary tract. Gallstones are hard, pebble-like deposits that can form in the gallbladder or bile ducts. Cholangitis is an infection of the bile ducts, often caused by bacteria. Cancer of the biliary tract is a rare but serious condition that can lead to life-threatening complications.

Treatment[edit | edit source]

Treatment for biliary tract diseases varies depending on the specific condition and its severity. Treatments may include medication, lifestyle changes, or surgery. In some cases, a cholecystectomy, or removal of the gallbladder, may be necessary.
