What's the difference between mesentery and mesogastrium?
Mesentery
Definition:
(n.) The membranes, or one of the membranes (consisting of a fold of the peritoneum and inclosed tissues), which connect the intestines and their appendages with the dorsal wall of the abdominal cavity.

(n.) One of the vertical muscular radiating partitions which divide the body cavity of Anthozoa into chambers.
