The figure shows the caudal surface of a section through the stomach and spleen; a ventral view of the stom- ach, the liver having been cut away to leave the sectioned edges of the lesser omentum and plica vense cavee; and the caudal surface of the septum transversum and pleuro-peritoneal membrane. Upon the surface of the septum is indicated diagrammatically the attachment of the liver (based on figures of Mall and F. T. Lewis and model by H. C. Tracy). grows actively to the left and caudally and gives the omentum an appearance of being folded on itself between the stomach and the dorsal body wall (Fig. 193). The cavity of the lesser peritoneal sac is carried out between the folds of the greater omentum as the inferior recess of the omental bursa. From the cranial end of the sac there is constricted off a small closed cavity which is frequently persistent in the adult. This is the bursa infracardiaca and may be regarded as a.
