The esophagus opens into the left extremity of the stomachobliquely, by an aperture called the cardiac orifice; and atthe right extremity the stomach opens into the duodenum bya smaller aperture, called the •pyloric orifice. Between theseorifices are the two curvatures of the stomach, the one abovecalled the smaller, and the lower on the larger curvature. The Fig. wswiioa s? 5*.ti eiiMAcii tyo *.
