DISEASES OF THE DIGESTIVE SYSTEM. 



ANATOMY AND PHYSIOLOGY. 



(Horse.) 



The lips are the prehensile organs, the incisor teeth are the 

 nippers. The food passes back on the tongue, and while the ani- 

 mal is chewing, the salivary glands are stimulated to secrete 

 enormous quantities of saliva, which is poured out partly to 

 moisten the food and partly to digest it. Its digestive action is 

 amylol>1;ic, i. e., digests starch. It takes about 15 minutes for 

 the saliva to act. The food is then formed into a bolus, which 

 passes down the oesophagus to the stomach. 



In all monogastric animals the stomach is in a collapsed con- 

 dition before eating begins ; in ruminants some food is always 

 present in the stomach. In monogastrics the stomach is no 

 larger than the amount of food put into it. After the food en- 

 ters the stomach, the starch digestion goes on for a little time, 

 and some lactic acid is formed. The presence of the food stim- 

 ulates the gastric juice to flow; this juice contains hydrochloric 

 acid, and when its secretion is fully established, the starch di- 

 gestion ceases. As soon as the acidulation comes up to a cer- 

 tain point, the pylorus opens and the products of digestion 

 (now called chyme) pass out into the duodenum, where the bile
