  1. Ventral view of the heart. Cx40 positive working myocardium is shown in green, primary myocardium is depicted in grey. # Dorsal view; the splanchnic plexus is shown in light red and hepatic lumen in brown.
  2. Left lateral view.
  3. Left lateral view; the surface of the left atrium is cut, showing the atrial septum and the entrance of the pulmonary vein. The endoderm is transparent.
  4. The splanchnic plexus is interwoven with the hepatic lumen
  5. Within the endoderm several organs are developing.
  6. Ventral view showing the sinus venosus region with respect to the splanchnic (blue) and somatic (red) mesoderm
