What is the Difference between peritoneal and retroperitoneal body organs?

∙ 11y ago
The peritoneum ( /ˌpɛrɨtənˈiəm/) is the serous membrane that forms the lining of the abdominal cavity or the coelom-it covers most of the intra-abdominal (or coelomic) organs-inamniotes and some invertebrates (annelids, for instance). It is composed of a layer of mesothelium supported by a thin layer of connective tissue. The peritoneum both supports the abdominal organs and serves as a conduit for their blood and lymph vessels and nerves.
The abdominal cavity (the space bounded by the vertebrae, abdominal muscles, diaphragm and pelvic floor) should not be confused with the intraperitoneal space (located within the abdominal cavity, but wrapped in peritoneum). The structures within the intraperitoneal space are called "intraperitoneal" (e.g. the stomach), the structures in the abdominal cavity that are located behind the intraperitoneal space are called "retroperitoneal" (e.g. the kidneys), and those structures below the intraperitoneal space are called "subperitoneal" or "infraperitoneal" (e.g. the bladder).

Do retroperitoneal organs have both a serosa and adventitia?
Retroperitoneal organs have only an adventitia. Peritoneal organs have only a serosa.
What is the term for organs that lie within the abdominal cavity but not within the peritoneal cavity?
An organ can be in the abdominopelvic cavity but not the peritoneal cavity if the organ sits below the diaphragm but outside the peritoneal membranes. The kidneys, which are behind the peritoneal membrane (retroperitoneal) are such organs.
What is the division of the abdominal cavity containing those organs posterior to the peritoneal lining?
The retroperitoneal space contains organs in the abdominal cavity that are behind the peritoneal lining.
What organs are inferior to the diaphragm lateral to the vertebral column and behind the peritoneal cavity?
The kidneys are in the retroperitoneal space, located inferior to the diaphragm, lateral to the vertebral column, and deep to the peritoneal cavity.
Briefly explain the difference between an adventitia and a serosa?
well, peritoneal structures like the bowel {i.e. located within the peritoneal cavity} are covered by serosa, a mesothelium type of cells. other organs {i.e. retroperitoneal, behind the peritoneum} like the oesophagus are covered with loose connective tissue called adventitia.

Difference between Peritoneum and abdominal cavity?
The abdominal cavity contains most of the digestive organs whereas the peritoneal cavity is the space between the parietal and visceral layers.
Why are the kidneys retroperitoneal?
Organs are retroperitoneal if they have peritoneum on their anterior side only. Structures that are not suspended by mesentery in the abdominal cavity and that lie between the parietal peritoneum and abdominal wall are classified as retroperitoneal.
Are the kidneys anatomically located ventrally within the abdomen?
The kidneys are located behind (posterior to) the abdominal cavity, in the retroperotoneum.Yes, the kidneys are located outside of the peritoneal cavity. In anatomy, they are referred to as being "retroperitoneal".No. Unlike the other abdominal organs, the kidneys lie behind the peritoneum that lines the abdominal cavity and are thus considered to be retroperitoneal organs.Yes
Where is the retro perineal cavity located?
The retroperitoneal cavity is located immediately posterior to the abdominal cavity (behind). It contains the kidneys (and so also the adrenal glands), the pancreas, and the abdominal aorta and vena cava. The walls of the abdominal cavity are covered with a serous membrane, called the peritoneum, as are most internal organs. The fluid in the membrane protects these structures and reduces friction between the organs and the cavity walls as well as between the organs themselves. The retroperitoneal space is separated from the peritoneal space by this layer of membrane covering the anterior organs e.g. liver, stomach, intestines. Both spaces are within the abdominal cavity.
What is the peritoneal?
The peritoneal layer is the layer of tissues within the body that protects vital organs, particularly the intestines and surrounding organs.
What is retroperitoneal?
Is the anatomical space behind (retro) the abdominal cavity.Structures that lie behind the peritoneum are termed retroperitoneal.Kidneys, Bladder, Pancreas, Vena Cava, Aorta, parts of the Duodenum, portions of the Colon, Reproductive organs.In your abdominal cavity is a membrane called the peritoneum, the intermost lining is the visceral peritoneum, which adheres to and supports the organs. the parietal peritoneum is the outer lining that adheres to the walls of the abdominal cavity. There is a space in between the two linings that has a potential for space that some organs actually lie in or are partialy in which is called the peritoneal cavity. those organs are said to be RETROPERITONEAL.
Is the spleen retroperitoneal?
No, the gall bladder is an abdominal organ that is contained within the peritoneum. The retroperitoneal organs are the kidneys, adrenal glands and the ureters - they are outside of the peritoneum.
