PANCREAS. 
A glandular body of a long jure, compared to a dog’s tongue, ~ 
Phas. under the oe ee composed of pee smal]] 
glands, the excretory duets of which unite, and form the pancreatic 
duct. This duct perforates the duodenum with the biliary duct, and 
conveys its secretion into the intestines. Use, to secrete a humour 
similar to saliva, and carry it into the duodenum, 
THE MILK VESSELS; 
_ The absorbing vessels of the mesentery, are so termed, because 
they convey the chyle, or milk-like fluid, from the intestines into the 
chest duct. They originate from the surface of the duodenum, or 
second stomach, the énipty, arid the twisted portion of the intestines ; 
and terminate in the chest duct, or trunk of the absorbénts, which 
runs near the fountain on the spine, and empties its contents into the 
jugular vein. . ks Bee 
As they run through the mesentery they pass through a number of _ 
glands, in which the chyle is altered, and then proceed to their 
trunk. Use, to carry the chyle from the intestines into the blood. 
KIDNEYS, So 
Two viscera, which setrete the urine, situated behind the wa ee
