'''Ventral mesentery''' is the part of the [[peritoneum]] closest to the [[navel]].
==Development==
The cephalic portion of the [[septum transversum]] takes part in the formation of the [[Thoracic diaphragm|diaphragm]], while the caudal portion into which the liver grows forms the ventral mesentery (or '''ventral mesogastrium''', when referring to the portion at the stomach).<ref name=gray> Gray's anatomy </ref>
The [[lesser omentum]] is formed, by a thinning of the mesoderm or ventral mesogastrium, which attaches the [[stomach]] and [[duodenum]] to the anterior [[abdominal wall]]. By the subsequent growth of the [[liver]] this leaf of mesoderm is divided into two parts, viz., the [[lesser omentum]] between the stomach and liver, and the [[falciform]] and [[coronary ligament]]s between the liver and the abdominal wall and diaphragm.<ref name=gray/>
