This fluid functions to pull down the friction between the abdominal viscera hence allowing for sack of contents during digestion. The variety meat of the abdominal cavity be classified either intraperitoneal or retroperitoneal. Intraperitoneal variety meat ar ones, which invaginate into the peritoneal cavity during embryonic development more like the lungs in the pleural cavity. Retroperitoneal organs are ones, which are posterior to the peritoneal cavity (outside the peritoneal cavity). These organs do parietal peritoneum on their anterior surfaces. phylogenesis of wild cloying pea and peritoneal cavity Embryonic development involves the validation of the trinity germ layers ( ectoderm, endoderm, and mesoderm.

Each of their embryonic tissues gives rise to a special(prenominal) tissue type that we see in humans today. Derivatives of fore goats rue The derivatives of the foregut is supplied by the coeliac artery (or branches off), whi ch comes directly off the aorta. These struc! tures include: oesophagus, stomach, and proximal part of the duodenum, liver and pancreas. Derivatives of midgut The derivatives of midgut are supplied by the superior mesenteric artery (or branches off) which comes directly from the aorta. The structures that form part of this area of the gut include: distal duodenum, jejunum, ileu m and large intestine recollect to left colic flexure.
