What is the function of the parietal peritoneum?

What is the difference between omentum and peritoneum?
The main difference between omentum and peritoneum is that omentum is an abdominal structure formed from the visceral peritoneum with a structure similar to the mesentery whereas peritoneum is the thin, serosal membrane, which lines the abdominal and pelvic cavities, covering most of the viscera.
What organs does the omentum cover?
It is composed of many folds that pass between or around the various organs. Two folds are of primary importance: the omentum, which hangs in front of the stomach and intestine; and the mesentery, which attaches the small intestine and much of the large intestine to the posterior abdominal cavity.
What organ is visible just below the peritoneal membrane?
Retroperitoneal Structures Other organs located in the retroperitoneal space are the kidneys, adrenal glands, proximal ureters, and renal vessels. Organs located below the peritoneum in the subperitoneal space include the lower third of the rectum and the urinary bladder.
Are your organs just floating?
Body surfaces not only separate the outside from the inside but also keep structures and substances in their proper place so that they can function properly. For example, internal organs do not float in a pool of blood because blood is normally confined to blood vessels.
Can the mesentery be removed?
While parts of the mesentery may be removed due to illness or injury, removing the entire mesentery is not possible. And when something goes wrong with the mesentery it can cause problems for the whole system. “A variety of problems can develop in the mesentery,” says Adler.
Are organs attached to anything?
It’s mainly the peritoneum that holds all the organs in place. Also the blood vessels are delivered from the bramches of the aorta via the mesentery(2 layers of peritoneum) which keep the intestines in place. Other than that, there is connective tissue and ligaments which keep the organs in their places.
