of this half is in contact with the spleen (¢). The other half 
(a) lies in the duodenal omentum between the limits of the 
duodenal U (c) and reaches to the bottom of the U. The 
pancreas has two ducts. The larger pancreatic duct (4) 
(sometimes known as the duct of Wirsung) collects the pan- 
creatic fluid from both halves of the gland, the ductlets from 
each half uniting to make two larger ducts, which then unite 
near the angle of the gland to make the pancreatic duct. This 
is short and broad and opens into the ampulla of Vater together 
with the common bile-duct. The accessory pancreatic duct

(duct of Santorini) opens into the duodenum about two centi- 
meters caudoventrad of the ampulla of Vater. It is formed by 
the union of branches which anastomose with those of the 
pancreatic duct. It is apparently sometimes lacking. 
Spleen. Lien.—The spleen (Fig. 102, ¢) is a deep red, 
flattened, elongated gland belonging to the lymphatic system. 
One of its ends, the left, lies against the free end of the gastric 
half of the pancreas and is broader than the other end. The 
spleen is curved and is suspended in the descending limb of the 
great omentum so that it follows the greater curvature of the 
stomach (d),
