Bile Duct
Conducto biliar
How do the bile ducts connect?
According to the National Cancer Institute (NCI), the smallest ducts inside the liver, called ductules, come together to form the right and left hepatic ducts, which lead out of the liver. The two ducts join outside the liver and form the common hepatic duct. The cystic duct from the gallbladder joins the common hepatic duct to form the common bile duct, which passes through the pancreas and ends in the small intestine.
What can block the bile ducts?
MedlinePlus says different diseases can block the bile ducts and cause a problem with the flow of bile. Its list includes gallstones, cancer, infections, birth defects such as biliary atresia, and inflammation, which can cause scarring.
What it means
A bile duct is a tube through which bile passes in and out of the liver. The liver makes bile, a digestive juice that helps break down fat, and the gallbladder stores it between meals. When a person eats, the gallbladder pushes the bile into tubes called bile ducts, which carry it to the small intestine. The National Cancer Institute describes two groups: intrahepatic bile ducts, a network of small tubes that carry bile inside the liver, and extrahepatic bile ducts, small tubes that carry bile from the liver and gallbladder to the small intestine. Different diseases, among them gallstones, cancer and infections, can block the bile ducts and cause a problem with the flow of bile. In Spanish the term is conducto biliar.

Conducto biliar is the headword of the National Cancer Institute's Spanish dictionary, which defines it as each of the tubes that carry bile inside the liver and out of it. Conducto is masculine: the same entry's captions write el conducto cístico and los conductos biliares hepáticos. The entry adds that a conducto biliar is also called canal biliar and vía biliar. MedlinePlus en español uses a different word, ductos biliares, and titles its page Enfermedades de los ductos biliares, with Enfermedades de las vías biliares under other names.
For the individual ducts, the NCI's Spanish captions use conducto hepático común (common hepatic duct), conducto cístico (cystic duct) and conducto colédoco (common bile duct). They call the two groups vías biliares intrahepáticas and vías biliares extrahepáticas. Related words in MedlinePlus en español are bilis (bile), vesícula biliar (gallbladder) and cálculos biliares (gallstones).
