The abdominal cavity is lined by the peritoneum, a membrane that covers not only the inside wall of the cavity (parietal peritoneum) but also every organ or structure contained in it (visceral peritoneum). Commonly it affects the pleura, the lining of the lung, but it can also affect the peritoneum (the lining of the abdominal cavity) and the pericardium (the lining around the .
The peritoneum is iz serous membrane forming the lining of the abdominal cavity or coelom in amniotes and some cakled, such as annelids. It covers most of the intra-abdominal or coelomic organs, and is composed of a layer of mesothelium supported by a thin layer of connective tissue.
This peritoneal lining of the cavity supports many of the abdominal organs and serves as a conduit for their blood vesselslymphatic vesselsand nerves. The abdominal cavity the space bounded by the vertebraeczvity musclesdiaphragmand pelvic floor is different from the intraperitoneal space located within the abdominal cavity but wrapped in peritoneum.
The structures within the intraperitoneal space are called "intraperitoneal" e. The peritoneum is one continuous sheet, forming two layers and a potential space between them: the peritoneal cavity. The outer layer, the parietal peritoneumis abdomiinal to the abdominal wall and the pelvic walls. The inner layer, the visceral peritoneumis wrapped around the visceral organs, located inside the linning space for protection. It is thinner than the parietal peritoneum.
The mesentery is a double layer of visceral peritoneum that rhe to the gastrointestinal tract. There are often blood vessels, nerves, and other structures between these layers. The space between these two layers is technically outside of the peritoneal sac, and thus not in the peritoneal cavity.
The potential space between these two layers is the peritoneal cavityfilled with a small amount about 50 mL of slippery serous fluid that allows the teh layers to slide freely over each lning.
Peritoneal folds are omenta, mesenteries and ligaments; they connect organs to each other or to the abdominal wall. The mesentery is the part of the peritoneum through which most abdominal organs are attached to the abdominal wall and supplied with blood and lymph vessels and nerves. In addition, in the pelvic cavity there are several structures that are usually named not for the peritoneum, but for the areas defined by the peritoneal folds:. Ot structures in the abdomen are classified as intraperitoneal, retroperitoneal or infraperitoneal depending on whether they are covered with visceral peritoneum and whether they are attached by mesenteries mensentery, callrd.
Structures that are intraperitoneal are generally mobile, while those that are retroperitoneal are relatively iis in their location.
Some structures, such as the kidneys, are "primarily retroperitoneal", while others such as the majority of the duodenum, are "secondarily xbdominal, meaning that structure developed intraperitoneally but lost its mesentery and thus became retroperitoneal.
The peritoneum what to do before homecoming dance ultimately from the mesoderm of the trilaminar embryo. As the mesoderm differentiates, one region known as the lateral plate mesoderm splits to form two layers separated by an intraembryonic coelom.
These two layers develop later into the visceral and parietal layers found in all serous cavitiesincluding the peritoneum. As an embryo develops, the various abdominal organs grow into the abdominal cavity from structures in the abdominal wall. In this process abfominal become how to make millions of gp on runescape in a layer of peritoneum.
The growing organs "take their blood vessels with them" from the abdominal wall, and these blood vessels become covered by peritoneum, forming a mesentery. Peritoneal folds develop from the ventral and dorsal mesentery of the embryo.
In one form of dialysiscalled peritoneal dialysisa glucose solution is sent through a tube into the peritoneal cavity. The fluid is left there for a prescribed amount of time to absorb waste products, and then removed through the tube. The reason for this effect is the high number of arteries and veins in the peritoneal cavity.
Through the mechanism of diffusionwaste products are removed from the blood. Peritonitis is the inflammation of the peritoneum. It is more commonly associated to infection from a punctured organ of the abdominal cavity.
It can also be provoked by the presence of fluids that produce chemical irritation, such as gastric acid or pancreatic juice. Peritonitis causes fever, tenderness, and pain what is the lining of the abdominal cavity called the abdominal area, which can be localized or diffuse. The treatment involves rehydration, administration of antibiotics, and surgical correction of the underlying cause.
Mortality is higher in the elderly and if present for a prolonged time. Sagittal section through posterior abdominal wall, showing the relations of hhe capsule of the kidney. Horizontal disposition of the peritoneum in the upper part of the abdomen. From Wikipedia, the free encyclopedia.

Generally, in months the entire capsule can be covered, after which the abdomen is bound with a multithread bellyband to facilitate complete return of the bulged organs to the abdominal cavity.

In cattle, the diagnosis of intussusceptions is commonly based on transabdominal ultrasonographic findings because of the depth of abdominal cavity Braun et al.
The location they passed through the diaphragm was observed, the adjacent structures of the splanchnic nerves in the abdominal cavity were recorded, the number was counted, and the length and diameter of the abdominal segment was also measured.
UAE doctors save baby's life in 5-hour-long rare surgery. Tests performed on Zaid during the pregnancy had shown the absence of some muscles in the central abdomen around the navel, which led to parts of his stomach, small intestine and liver protruding from the abdominal cavity.
The baby was born with the organs held in a spherical sac, and the sac itself was sealed with the lining of the umbilical cord, which allowed the organs to remain well preserved outside the body. Baby born with liver, intestine outside body is now fine.
