THE ALIMENTARY CANAL. 241 



its dorsal surface is adapted to the suprarenal body. The 

 caudate or Spigelian lobe (Fig. loi, c) is an elongated, tri- 

 angular, pyramidal lobe. It lies in the omental sac and partly 

 closes the foramen cpiploicum (foramen ofWinslovv). At its 

 base it is connected with the caudal division of the right lateral 

 lobe {d'). 



The Gall-bladder (Fig. \oi,f) is pear-shaped and lies in 

 a cleft on the caudal (or dorsal) surface of the right median 

 lobe {c, t '•) of the liver. Its larger end is directed caudad (or 

 ventrad) and is free. By one surface it is in contact with the 

 liver and not covered by peritoneum, while the other surface 

 is covered by peritoneum. The peritoneum in passing from 

 the larger free end to the liver forms one or two ligament-like 

 folds. By its smaller end the gall-bladder is continuous with 

 the cystic duct [g-). This duct is about three centimeters long 

 and has a sinuous course. At its distal end it is joined by two 

 (or more) hepatic ducts (//), bringing the bile from the lobes 

 of the liver. The relation of these to the cystic duct varies. 

 They may open into it by a common trunk or separately. Of 

 these hepatic ducts one is made up by the junction of smaller 

 hepatic ducts from the left half of the liver and the left half of 

 the cystic lobe, while the other is similarly formed by smaller 

 ducts from the right half of the cystic lobe, from both divisions 

 of the ritrht lateral lobe and from the caudate lobe. The duct 

 formed by the junction of the hepatic and cystic ducts is the 

 common bile-duct (ductus communis choledochus) (/). It 

 passes in the free right border of the gastroduodenal omentum 

 to the duodenum (/') and opens into it by way of the ampulla 

 of Vater, in common with the pancreatic duct, at a point on 

 the dorsal surface of the duodenum and about three centimeters 

 from the pylorus. 



Pancreas. — The pancreas (Fig. 102, a) is a flattened, 

 closely lobulated gland of irregular outline, about twelve centi- 

 meters long, varying in width from one to two centimeters. 

 It is bent nearly at right angles at about its middle. One of 

 the halves (^a) into which it is divided by its bend lies in the 

 descending limb of the great omentum, and is near the greater 

 curvature of the stomach {ci) and parallel to it. The free end
