Our home physician: a new and popular guide to the art of preserving health and treating disease; with plain advice for all the medical and surgical emergencies of the family . o the stomach. The stomach is a highly irritable and sensitiveorgan, having numerous muscular fibres entering into its composition,and being plentifully supplied with nerves. On its outside it iscovered by a membrane called peritonaeum, because it lines the abdo-men, and contains the different digestive organs within its fold. This THE INTESTINES 139 membrane not only sustains those organs in their proper situations,but also affords a fine mucous fluid for keeping their surfaces con-stantly moist, thusto prevent injuries^fi(Bii • which would other- wise arise from fric-tion. From the in-ternal surface of thestomach there is afluid constantly se-creting, called thegastric juice, whichhas the peculiar pro-perties of dissolvingand attenuating thefood before it passesinto the intestines.

II Folds of mucous membrane of THE INTESTINES. The intestines are a long membranous and muscular canal, whicharises from the right orifice of the stomach, and is generally five orsix times the length of the body, forming many circumvolutions inthe cavity of the abdomen,, which it traverses from right to left, andagain from left to right. Their structure is not unlike that of thestomach, being composed partly of muscular and nervous fibres, andpossessing a high degree of irritability, as may be seen by their worm-like motions, even out of the body after death, when pricked with aneedle, or otherwise stimulated. Soon after the intestinal canal goesout from the stomach, an oblique opening may be perceived by whichthe fluids from the pancreas and liver are poured into the intestinefor the purpose of mixing with the food as it passes
