1085. THE PANCREAS is an oblong racemose gland 

 (Figs. 101, 102), constructed of sinewy, secretory, and 

 nervous tissue, situated above the transverse duodenum, 

 and opening into it. 



1086. THE USE OF THE PANCREAS is to secrete a 

 fluid called pancreatic juice, having the general appear- 

 ance of saliva. 



1087. THE USE OF THE PANCREATIC JUICE is to form 

 an emulsion with fat, and thereby enable it to enter and 

 mingle with the blood, which alone it could not do. 



1088. BRUNNER'S GLANDS are minute racemose 

 glands in the walls of the duodenum, apparently of the 

 same character as the pancreas, and secreting the same 

 kind of fluid.
