The greater por- tion of the liver is covered by a closely adherent layer of per- itoneum, which is continued to form at- tachments with the pericardium, ventral body wall, dorsal body wall, and the stomach and intestine. The bile duct is formed by the confluence of the hepatic. Fig. 42. â Liver and pancreas of frog.
