*The mesoderm forms the skeletal muscle ([[Oesophagus - Anatomy & Physiology|oesophagus]] and anus), smooth muscle (lateral plate mesoderm) and connective tissue layers around the inner endoderm.

5. The dorsal mesogastrium becomes elongated (with the spleen) and expands into a large fold along the ventral abdominal wall. This becomes the greater omentum which covers all the abdominal organs. It is a superficial structure which is free to move.

6. The ventral mesogastrium becomes the lesser omentum. It is in between the stomach and the liver. The rest of the ventral mesentry degenerates.
