Bile duct

Bile Duct

The bile duct is a tubular structure in the body that carries bile from the liver and gallbladder to the small intestine. Bile is a fluid produced by the liver that aids 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. It then passes through the pancreas before emptying into the small intestine at the ampulla of Vater.

Function

The primary function of the bile duct is to transport bile from the liver and gallbladder to the small intestine. Bile is crucial for the digestion and absorption of dietary fats. It also helps in the excretion of certain waste products from the body, including bilirubin, a byproduct of red blood cell breakdown.

Diseases and Disorders

There are several diseases and disorders that can affect the bile duct, including bile duct cancer, gallstones, and primary sclerosing cholangitis. These conditions can lead to symptoms such as jaundice, abdominal pain, and weight loss. Treatment options vary depending on the specific condition and may include medication, surgery, or other interventions.
