  Abdominal cavity  The abdominal cavity is divided into two
major compartments early in foetal development (the peritoneum
and retroperitoneum).  The parietal peritoneum is reflected over
the peritoneal organs to form a series of supporting ligaments,
mesenteries and omenta. The peritoneal reflections
carry vessels, nerves and lymphatics from the retroperitoneum to
the peritoneal organs. They may act as a natural
connection between the retroperitoneum and peritoneum
(the subperitoneal space) which provides a pathway for the
extension of intraabdominal disease.  Mesentry, omenta
and peritoneal ligaments are formed as the peritoneum is
reflected within the abdominal cavity.  Related articles
