. The comparative anatomy of the domesticated animals. Veterinary anatomy. 510 THE DIGESTIVE APPARATUS IN MAMMALIA. In the Dog and Cat, the liver is very voluminous, is deeply notched, and is divided into five principal lobes. The middle lobe has the gall-bladder attached to it, and gives it complete lodgment in a fossa. In the Dog, the ductus choledochus, joined to a small branch from the pancreatic duct, enters the intestine at a variable distance from the pylorus, depending upon the size of the animal, but usually between IJ and 4f incht s. In the portion comprised between the intestine and the origin of the cystic duct, it receives several biliary canals of somewhat considerable diameter. In the Cat, the ductus choledochus is most frequently inserted from about 1 to IJ inches from the pyloric orifice; it opens immediately alongside the pancreatic duct, when it does not join it. â u ⢠2. In the Ox, the pancreas is not placed across the sublumbar parietes, but is comprised between layers of the mesentery, to the right of the great mesenteric artery. The excretory duct is single, and opens into the small intestine at from 14 to 16 inches beyond the ductus choledochus. In the Sheep and Goat, there is the same general arrangement, but the excretory ducts opens with that of the liver. In the Pig, a portion of the pancreas is situated in the sublumbar region, between the large tuberosity of the stomach and the last fiexure of the colon ; the other portion is lodged in the duodenal fraenum.
