Physiology 19. Prehension of food. — The taking of food comes first in an enumeration of the physiological processes by means of which ani- mals are productive. The chief prehensile organ in the horse is the lip, in cattle and sheep the tongue, and in the hog the snout. 20. Digestion. — In the mouth the food is comminuted by masti- cation so as to be more completely accessible to the digestive juices, and is acted upon by the saliva which com- mences the digestion of some of the starches. This is continued after the food is swallowed into the stomach. Here also the gastric juices, with their enzymes, and the hydrochloric acid, continue the conversion of the raw materials of nutrition presented in the food into forms in which they may be assimilated into the blood stream and become available to the tissues and to such secreting organs as the udder. Digestion is completed in the small. Fig. 7. — Surface of mucous membrane of the intestine.
