THE STOMACH The stomach is large; its average capacity is about IJ^ to 2 gallons (ca. to 8 liters). When full, its long axis is transverse and its greater curvature extends backward on the floor of the abdomen a little further than a point midway Difcrli- culuin Pylorus (Esophagus.

The left part is large and rounded, while the right part (Pars pylorica) is small, and bends sharply upward to join the small intestine. The parietal surface faces chiefly forward, and is related to the liver and diaphragm. The visceral surface faces chiefly backward, and is related to the intestine, greater omentum, mesentery, and pancreas. The greater cur- vature is related to the diaphragm, spleen, liver, and abdominal floor. The pyloric end lies against the right lateral lobe of the liver, about opposite to the middle of the next to the last intercostal space. The left extremity is opposite to the last intercostal space or preceding rib, and is related to the dorsal end of the spleen and the left extremity of the pancreas; it presents a flattened conical blind pouch, the diverticulum ventricuU, the apex of which projects backwar
