Diagram Of Liver And Bile Ducts

A bile duct is any of a number of long tube like structures that carry bile and is present in.

Diagram of liver and bile ducts. The bile ducts are a series of tubes that drain bile from the liver and either direct it to the gallbladder for temporary storage or pass it into the duodenum where it can be expelled with the feces. When the liver cells secrete bile it is collected by a system of ducts that flow from the liver through the right and left hepatic ducts. Vaginali ductuli are small communications between two bile ducts or between a bile duct and. These ducts ultimately drain into the common hepatic duct.

Connected to the bile ducts of the liver through the cystic duct the gallbladder receives bile transported from the liver for storage on a regular basis to prepare for the digestion of future meals. The common hepatic duct then joins with the cystic duct from the gallbladder to form the common bile duct. The excess sits in the hepatic and cystic ducts which are connected to the gallbladder. After meals the gallbladder is empty and flat like a deflated balloon.

A bile duct obstruction also known as biliary obstruction is when one of the ducts that carry bile from the liver to the intestine via the gallbladder becomes blocked. The gallbladder stores bile produced by the liver. Bile ducts thus begin in very close proximity to the terminal branches of the portal vein and hepatic artery and this group of structures is an easily recognized and important landmark seen in histologic sections of liver the grouping of bile duct hepatic arteriole and portal venule is called a portal triad. During digestion of a meal smooth muscles in the walls of the gallbladder contract to push bile into the bile ducts that lead to the duodenum.

The biliary tree as it is known has many different parts all of which serve the same function and are prone to a number of diseases that can ultimately affect the liver gallbladder and or pancreas. The common bile duct is a small tube like structure formed where the common hepatic duct and the cystic duct join.
