PANCREAS 125 



covered area" is a small triangular impression made by the 

 right suprarenal capsule, and to the left of this a deep groove 

 into which fits the vena cava. To the left of the vena cava lies 

 the Spigelian lobe, a small prominent portion of liver substance. 

 To the left -of the Spigelian lobe lies the groove for the osso- 

 phagus. 



The Visceral surface is a sloping surface looking obliquely 

 downwards, backwards, and to the left. It lies upon the 

 stomach, intestines, and right kidney. 



The visceral surface of the left lobe lies on the cardiac portion 

 of the stomach and the lesser curvature where the small omentum 

 is attached. The stomach makes a deep concave impression on 

 the liver, and above, the liver substance bulges out, forming the 

 omental tuberosity. The visceral surface of the right lobe is 

 divided into two portions by the gall-bladder, the portion on the 

 left being called the quadrate lobe. Between the left lobe and 

 the quadrate lobe is the portal fissure, to which the small omen- 

 tum is attached. In the portal fissure lie the portal vein, 

 hepatic veins, and hepatic artery. On the right of the gall 

 bladder are three impressions that of the duodenum just above, 

 and to the right that of the right kidney, and below, the hepatic 

 flexure of the colon (see Fig. 49). 



The Hepatic Duct is formed by the union of the ducts from 

 the right and left lobes, and joined by the cystic duct from the 

 common bile-duct, which lies in the portal fissure. 



The Gail-Bladder is a diverticulum of the bile-duct to form a 

 reservoir for the bile. It is a pear-shaped bag, the wide end of 

 which usually protrudes below the inferior border of the liver 

 and touches the abdominal wall at the level of the ninth costal 

 cartilage on the right side. 



The Pancreas is a long, narrow gland lying transversely on 

 the posterior abdominal wall. It has no true capsule, so 

 the lobulations are apparent. In shape the pancreas can be 

 compared to a J turned on its side thus c.. It is divisible 

 into a head, body, and tail. The head lies in the curve of the 

 duodenum, the body on the posterior abdominal wall crossing 

 in front of the left kidney, and the tail comes in contact with the 

 spleen. Behind the head of the pancreas are the vena cava and
