The esophagusleads into the stomach from above, through an opening calledthe cardiac orifice. The small intestine begins at an openingat the small end of the stomach, called the pylorus (gate-keeper). These openings are guarded by bands of muscles,which keep the openings closed so as to hold the food in thestomach for the proper length of time. When food enters the stomach, this organ is excited, andarouses from a quiet condition to one of activity. The bloodflows to it in increased amount, so that its inner coat turnsfrom a pale color to a deep red. The lining membranebecomes filled with the blood that flows into its minuteblood-vessels. In this inner coat there are multitudes of DIGESTION. 63. tiny glands, called gastric glands. When the blood flowsfreely to the stomach, these gastric glands readily secretelarge quantities of gastric fluid upon the food, just as thesalivary glands pour out saliva in the The gastricjuice consists ofwater, containingsome mild acids,and a peculiar sub-stance called pep-sin. It is by theaction of the pepsinin the warm acid flu-ids of the stomachthat the albuminoidfoods are foods are allmore finely dividedand dissolved by thewarm liquids and by the constant motion of the stomach. As the albuminoids are prepared to enter the blood, theygradually pass directly through the mucous lining of thestomach into the blood-vessels. The gastric juices are inlike manner re-absorbed into the blood. After being passedthrough the liver to the heart, the food finds its way to allparts of the body, so that hunger is soon gratified, and thestrength of the body is increased. Such po
