. The comparative anatomy of the domesticated animals. Veterinary anatomy. THE STOMACH. 395 lobo of the right sac; above, it receives the insertion of the oesophagus, and is continuonsj in front, with the reticulum. Belatione.—The external form of the rumen being rletermined, the study of its relations becomes easy. By its superior surface, it is in contact with tlie intestinal mass ; its opposite face rests on the inferior abdominal wall. Its left border, supporting the spleen, touches the most elevated part of the flank and the siiblumbar region, to which it adheres by cellular tissue, as well as the vicinity of the coeliao trunk and the great mesenteric artery; the right border, maigined by the abomasum, responds to the most declivitous portion of the right hypochondriac and flank, as well as to the intestinal circumvolutions. The anterior extremity, bounded by the reticulum and omasum, advances close to the diaphragm; the posterior occupies the entrance to the pelvic cavity, where it is more or less in contact with the genito-urinary oigans lodged there. In the pregnant female, the uterus is prolonged lorwards on the "upper face of the viscus just described. Interior (Fig. 193).—In the interior of the rumen are found incumplete septa, which repeat the division into two sacs already so marked externally. These septa are two iu Fig. INTERIOR OF THE STOMACH IN EOTINANTS; THE UPPER PLANE OP THE ETOEN INTERIOR OP T^^^ ^^^^^^j^^^^ ^HH THE CESOPHAGEAl PHBROW.
