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

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

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

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

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.
