Its physiological role is to carry bile from the gallbladder and empty it into.

Gallbladder and common bile duct anatomy. The common bile duct travels initially in the free edge of the lesser omentum then courses posteriorly to the duodenum and pancreas to unite with the main pancreatic duct to form the ampulla of vater which drains at the major duodenal. Made for unideb 2017. Variations of the cystic duct include a long parallel course with low insertion into the common duct insertion into the left side of the common duct and drainage into a right hepatic duct.

It functions as an accessory organ by concentrating the bile and transporting it to the duodenum via the common bile duct aiding in digestion and fat absorption. The common bile duct sometimes abbreviated cbd is a duct in the gastrointestinal tract of organisms that have a gall bladder. Rarely an accessory hepatic duct may enter the gallbladder.

Variations in bile duct anatomy do not necessarily parallel variations in portal venous anatomy. The common hepatic duct is joined by the cystic duct from the gallbladder to form the common bile duct. 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.

It is formed by the union of the common hepatic duct and the cystic duct from the gall bladderit is later joined by the pancreatic duct to form the ampulla of vaterthere the two ducts are surrounded by the muscular sphincter of oddi. Anatomy of gall bladder. As the common hepatic duct descends it is joined by the cystic duct which allows bile to flow in and out of the gallbladder for storage and release.

The cystic ductwhich communicates with the gallbladder joins the common hepatic duct to form the common bile duct or known just as the bile duct. The bile duct which is between 5 to 15 centimeters long courses behind the top of the duodenum and pancreas until it runs side by side with the main pancreatic duct. The common hepatic duct then joins with the cystic duct from the gallbladder to form the common bile duct.

The common bile duct is a small tube like structure formed where the common hepatic duct and the cystic duct join. From its commencement at the neck of the gallbladder it passes posteriorly inferiorly and medially to join the common hepatic duct to form the common bile duct the mucous lining of the cystic duct is often raised into a spiral fold called the spiral valve of heister see figure 2. At this point the common hepatic duct and cystic duct combine to form the common bile duct.

Please try again later. These ducts ultimately drain into the common hepatic duct. The cystic duct is 34 cm in length and approximately 3 mm wide.
