The ventral mesentery extends from the anterior end of the sinus venosus to the hind end of the fore-gut, where it unites with the ventral body-wall. It includes the sinus venosus and the ductus venosus, together with the hepatic diverticula. The median and lateral mesocardia, together with the ventral mesen- tery of the fore-gut, form a mass known as the septum Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Lillie, Frank Rattray, 1870-1947.
