CHYLIFICATION.

Fig. 23. 



13. The small intestine, 

 (Fiy 23, />/.) is next to the 

 stomach ; it is narrower than 

 the large intestine, and its ex- 

 ternal surface is smooth. Its 

 length is very considerable, 

 and it is sub-divided into three 

 portions, called : Duodenum, 

 Jejunum, and Ilium. 



14. In the small intestine, 

 the chyle is formed, and diges- 

 tion finished. 



15. The phenomenon of 

 chylification is produced by 

 the mixture of the chyme, 

 with the bile and the pancre- 

 atic juice. 



16. The bile, or gall is a 

 greenish and very bitter liquid, 

 secreted by the liver. 



17. The/iiw, (Fig. 22, /.; 

 is a large reddish gland, and 

 of a granular tissue. It is 

 lodged in the superior part of 



the abdomen, to the right of the stomach, and presents upon its 

 inferior surface, a membranous pouch called the aall bladder, (o/.) 

 The bile accumulates in this bladder, as in a reservoir, and is 

 afterwards poured into the duodenum by a narrow canal, called 

 the biliary duct, or ditctus conuuvnis chofedoc/ius. 



18. The pancreatic juice is a watery liquid which very much 

 resembles saliva; it is formed in a gland, situate behind the 

 stomach, which is called pancreas. It reaches the duodenum by 

 a narrow canal, which arises in the pancreas, and empties near 

 the opening of the biliary duct. 



19. The chyme, mixed with the bile and pancreatic juice, 

 passes through the whole length of the small intestine; and during 



13. What is the small intestine ? What are its sub-divisions? 



14. What takes place in the small intestine? 

 15 How is chylification produced? 



16. What is hile? 



17. What is the liver ? Where is it situated ? What part receives the bile 

 from the gall bladder. 



18. What is pancreatic juice? Where does this pancreatic juice go after 

 leaving the pancreas? 



19 What becomes of the chyme after being mixed with the bile and 

 pancreatic juice ?
