Biliary duct and gallbladder ·★Consists of Gallbladder, Left and right hepatic ducts Hepatic duct Common hepatic duct Common Common bile duct bile duct Enters the wall of descending part of duodenum obliquely where joins the main pancreatic duct to form the hepatopancreatic ampulla Opens at the major duodenal papilla
★ Biliary duct and gallbladder • ★ Consists of – Gallbladder, – Left and right hepatic ducts – Common hepatic duct – Common bile duct Enters the wall of descending part of duodenum obliquely where joins the main pancreatic duct to form the hepatopancreatic ampulla • Opens at the major duodenal papilla
☆Gallbladder ·★Position Lies in fossa for gallbladder on visceral surface of liver ·★Four parts 1.Fundus of gallbladder protrude below the inferior margin of the liver, behind the point where the lateral margin of the right rectus abdominis meets the costal arch(Murphy'point) 2.Body of gallbladder 3.Neck of gallbladder 4.Cystic duct Function:stores and concentrates bile
★ Gallbladder • ★ Position – Lies in fossa for gallbladder on visceral surface of liver • ★ Four parts 1. Fundus of gallbladder protrude below the inferior margin of the liver, behind the point where the lateral margin of the right rectus abdominis meets the costal arch (Murphy’ point) 2.Body of gallbladder 3.Neck of gallbladder 4. Cystic duct • Function: stores and concentrates bile
Biliary duct system Left and right hepatic ducts unite outside of liver to form common hepatic duct common hepatic duct Cystic duct joins common hepatic duct to form common bile duct
★ Biliary duct system • Left and right hepatic ducts unite outside of liver to form common hepatic duct • common hepatic duct • Cystic duct joins common hepatic duct to form common bile duct
★Biliary duct system Hepatopancreatic ampulla (Vater) Common bile duct and pancreatic duct run obliquely through the wall of the descending part of duodenum ,unite to form the hepatopancreatic ampulla---rounded by sphincter of hepatopancreatic ampulla (Oddi),has sphincteric muscle for regulating flow,opens at the major duodenal papilla Obstruction of the biliary system results in the clinic condition of jaundice(yellow skin)
