A section through the T-1 spinal ganglion and stomach.

Observe:
1. The dorsal and ventral mesogastrium attaching to the greater and lesser curvatures of the stomach, respectively.
2. The lesser sac dorsal to the stomach.
3. The junction of the portal vein with the ductus venosus.
4. Nearby afferent veins arising from the ductus venosus carrying blood to the hepatic sinusoids.
5. The edge of the gall bladder on the caudal surface of the liver.
