Bile ducts

Bile ducts are a series of thin tubes that go from the liver to the small intestine. The main function of the bile ducts is to transport bile, a fluid produced by the liver that helps in the digestion of fats.

Anatomy

The bile duct system is a complex network of smaller tubes that merge into larger ones, eventually forming the main bile duct, also known as the common bile duct. The common bile duct is formed by the union of the cystic duct from the gallbladder and the hepatic duct from the liver. The common bile duct then joins with the pancreatic duct to form the ampulla of Vater, which empties into the small intestine.

Function

The primary function of the bile ducts is to transport bile from the liver and gallbladder to the small intestine. Bile is a crucial substance that aids in the digestion and absorption of fats and fat-soluble vitamins in the small intestine. It also helps in the elimination of waste products from the liver.

Diseases

There are several diseases and conditions that can affect the bile ducts, including bile duct cancer, gallstones, and primary sclerosing cholangitis. These conditions can cause symptoms such as jaundice, itching, and abdominal pain, and may require treatments ranging from medication to surgery.
