Anatomy

Peritoneum and peritoneal cavity The peritoneum is a transpargonnt membrane that lines the stainless abdominopelvic cavity. It consists of dickens layers. The parietal peritoneum is the outer most layer of the peritoneum and this invests the inwrought walls of the abdominopelvic cavity. The intuitive peritoneum is the inner layer, which invests over abdominal viscera. Both layers be make of mesothelium, which is composed of simple squamous epithelium. The potential space in the midst of these twain layers of peritoneal lining is called the peritoneal cavity, which contains a thin claim of fluid called peritoneal fluid. This fluid functions to trim the friction between the abdominal viscera hence allowing for work shift of contents during digestion. The variety meat of the abdominal cavity be classified either intraperitoneal or retroperitoneal. Intraperitoneal variety meat be ones, which invaginate into the peritoneal cavity during embryonic development much(p renominal) like the lungs in the pleural cavity. Retroperitoneal organs are ones, which are posterior to the peritoneal cavity (outside the peritoneal cavity). These organs pick out parietal peritoneum on their anterior surfaces. phylogenesis of wild bouquet pea and peritoneal cavity Embryonic development involves the shaping 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 forecatgut The derivatives of the foregut is supplied by the coeliac artery (or branches off) , which comes directly off the aorta. These ! structures 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 esteem to left colic flexure.
