Anatomy

Peritoneum and peritoneal cavity The peritoneum is a transp arnt membrane that lines the intact abdominopelvic cavity. It consists of dickens layers. The parietal peritoneum is the outer most layer of the peritoneum and this invests the interior 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 sign up the friction between the abdominal viscera hence allowing for unsteady of contents during digestion. The variety meat of the abdominal cavity are classified either intraperitoneal or retroperitoneal. Intraperitoneal variety meat are ones, which invaginate into the peritoneal cavity during embryonic development a lot li ke the lungs in the pleural cavity. Retroperitoneal organs are ones, which are posterior to the peritoneal cavity (outside the peritoneal cavity). These organs withdraw parietal peritoneum on their anterior surfaces. phylogenesis of wild unused pea and peritoneal cavity Embryonic development involves the makeup 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), which comes directly off the aorta. These structures include: oesophagus, stomach, a nd 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 specify to left colic flexure.
