Note ventral anchoring of attachment site is at the most cranial extension of the septum transversum. Note the pleuroperitoneal fold on the medial side of the R common cardinal vein - this fold will form part of the diaphragm. Lateral extension of pulmonary mesenchyme is moulded to shape of coelomic canals. Prominent R pleuroperitoneal fold. Note dorsal extent of coelomic canals.
Oesophagus lumen reappears caudal to bifurcation.
Ovoid stomach with developing space of the lesser sac on R. Dorsal and ventral attachments of the mesenchyme are now known as dorsal and ventral mesogastria. Note change in outline of coelomic canals due to presence of liver. Note thick mesothelium lining the coelom along Ledge of stomach, the primordium of the spleen and greater omentum along greater curvature. Tracheal bifurcation dorsal to sinus venosus. Inferior vena cava.
