THE ALIMENTARY CANAL. 240 
its dorsal -surface is adapted to the suprarenal body. The 
caudate or Spigelian lobe (Fig. 1o1, ¢). is an elongated, tri- 
angular, pyramidal lobe. It lies in the omental sac and partly 
closes the foramen epiploicum (foramen of Winslow). At its 
base it is connected with the caudal division of the right lateral 
lobe (@’). 
The Gall-bladder (Fig. 101, /) is pear-shaped and lies in 
a cleft on the caudal (or dorsal) surface of the right median 
lobe (c, c’) 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 right 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) (2). It 
passes in the free right border of the gastroduodenal omentum 
to the dyodenum (4) 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 (@) and parallel to it. The free end
