DIGESTIVE SYSTEM OF THE PIG 



lateral border extends backward to the upper part of the twelfth intercostal space 

 or thirteenth rib. The left lateral border is opposite the eighth rib and intercostal 

 space. The ventral border extends backward about as far as the umbilicus. 



There are no lateral ligaments and the falciform ligament disappears early. 



The gall-bladder is attached in the fossa vesicae fellese on the right central lobe, 

 at a considerable distance from the ventral bordfer. The cystic duct joins the hepa- 

 tic 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. 



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 tissue is much less friable than that of the other animals, 

 from which it is easily distinguished.
