gland, lying directly behind the stomach. It is about six 

 inches in length, the right end of it being somewhat larger 

 than the left extremity, and hence called the head. To the 

 naked eye the lobular structure is apparent : but each lobule 

 is itself made up of much smaller lobules. The duct of the 

 Pancreas conveys the milk-like secretion of this gland, to 

 nearly the same point on the Duodenum as the Hepatic Duct, 

 where they both enter that tube in a slanting manner, so that 

 by the valvular arrangement the contents of the intestine can 

 not be forced backwards into the Biliary or Pancreatic duct.

 what mechanical structure in it makes it remarkable ?
