reach to the ventral border. The cystic duct joins the hepatic duct at an acute 

 angle immediately after the emergence of the latter from the portal fissure. The 

 bile duct (Ductus choledochus) opens at the papilla duodeni about one or two inches 

 (ca. 2.5 to 5 cm.) from the pylorus; an ampulla may be formed.

naturally be inferred from this figure, but are situated more medially and are covered laterally by small intestine. 



Owing to the large amount of interlobular tissue, the lobules are mapped out 

 sharply; they are polyhedral in form, and are 1 to 2.5 mm. in diameter. For the 

 same reason the gland is much less friable than that of the other animals, from which 

 it is easily distinguished.
