DIGESTIVE SYSTEM OF THE PIG 



The parotid gland is large and triradiate. It extends very little on to the mas- 

 seter muscle and its upper angle does not quite reach the base of the ear. It is

 face are several large subparotid lymph glands, some of which are only partially

covered by the parotid. The duct arises on the deep face, has a course similar

 along the course of the duct.
