and behind with the ist part of duodenum, and the hepatic 

 flexure of colon. The fundus is in contact with the parietes 

 opposite the gth right costal cartilage. 



The cystic duct passes from the neck of the gall-bladder 

 downwards, backwards, and to the left, to join the hepatic 

 duct at the mouth of the portal fissure. 



The hepatic duct, formed by union of ducts from right and 

 left lobes, issues from the liver at the bottom of the transverse 

 fissure. It joins the cystic duct, the two forming the common 

 bile-duct. Its length is i inch, and it lies entirely within the 

 portal fissure. 



The ductus communis ckoledoclms or common bile-duct 

 results from the union of the hepatic and cystic ducts. It 

 passes downwards in front of the foramen of Winslow in the 

 layers of the gastro-hepatic omentum, having the vena porta 

 behind, and the hepatic artery on the left. It then descends 

 behind the ist part of the duodenum, and, passing between 

 the pancreas and 2nd part of the duodenum where it lies on 

 the inferior vena cava, it enters the small intestine obliquely, 

 a little below the middle of the descending part of the duo- 

 denum, by an opening on the biliary papilla (p. 189) common 

 to it and the pancreatic duct. Length 3 inches. 

 Vessels of the liver : 



The hepatic artery from the coeliac axis enters the trans- 

 verse fissure and divides into two branches for the right and 

 left lobes. The right branch gives off the cystic branch to 

 the gall-bladder. 



The portal vein, having the hepatic artery on the left and in 

 front, and the common bile-duct on the right, ascends between 

 the layers of the gastro-hepatic omentum, in front of the fora- 

 men of Winslow, to the transverse fissure. The vessels, accom- 

 panied by nerves and lymphatics, are surrounded by areolar 

 tissue, the capsule of Glisson, which passes with them into the 

 liver. 



The hepatic veins pass out of the liver at the bottom of the 

 fissure of the inferior vena cava, immediately joining that 

 vessel. 



THE PANCREAS. 



Length : 6 to 8 inches. Consists of a body, enlarged to the 

 right at its head, with which the body is connected by a narrow 

 part or neck, and narrowed to the left, where it ends as the tail. 



Position. Placed in the epigastric and left hypochondriac 

 regions, directed transversely across posterior wall of abdomen.
