DIGESTIVE SYSTEM. 333 



The pancreas is a diffuse fat-like gland of a 

 pinkish colour, scattered in the mesentery of the 

 duodenal loop. It lies mainly around the large 

 vessels of the loop, and is more compact at its 

 anterior end. 



The pancreatic duct commences in front, and 

 runs backwards through the gland, receiving smaller 

 ducts from its several lobes ; it opens into the inner 

 side of the distal limb of the duodenal loop, about 

 three inches beyond the bend. 



Open the duodenum, opposite to the entrance of the pan- 

 creatic duct ; luash out the contents ; note the aperture of the 

 duct, and insert a bristle into it. 



4. The liver is a large solid organ, thick in the middle and 

 thinner towards the edges. Its anterior surface is 

 convex and fits against the diaphragm, to which it is 

 attached by a median vertical fold of peritoneum, 

 the suspensory ligament : its posterior surface is 

 concave, and lies against the stomach. 



a. The lobes of the liver. 



i. The left central lobe lies against the left half of 

 the diaphragm. 



ii. The left lateral lobe lies between the left cen- 

 tral lobe and the stomach, to the cardiac end 

 of which it is applied. It is the largest of the 

 lobes, and is partially subdivided. 



iii. The Spigelian lobe fits into the concave anterior 

 border of the stomach , and is much the smallest 

 of the lobes. 



iv. The right central lobe lies against the right 

 half of the diaphragm, and is grooved on its 

 posterior surface for the gall-bladder. 



V. The caudate lobe lies along the right side and 

 dorsal surface of the pyloric end of the 

 stomach. Its posterior margin is hollowed
