In the early embryo, the primitive gut tube is suspended by the dorsal and ventral mesogastria. The mesogastria divide the embryo into two cavities, called the left and right coelomic cavities. The ventral mesogastrium atrophies caudal to the pylorus of the [[Forestomach - Anatomy & Physiology|stomach]] and cranial to the [[Rectum - Anatomy & Physiology|rectum]]. This gives the entire small intestine and most of the large intestine large scope for expansion and rotation. It also allows the left and right coelomic cavities coalesce. This forms one cavity; '''the peritoneal cavity'''.

Peritoneal structures develop from the dorsal and ventral mesogastria.
