The easiest way to diagnose peritonitis is to extract a small amount of peritoneal fluid and perform microbiological analysis to confirm the presence of bacteria and inflammatory cells. Peritonitis is usually caused by intestinal bacteria which find their way to the peritoneum via lymph (lymphatic dissemination) or ruptured bowel. Because of this, a pair of cellular layers are produced. Peritonitis is an inflammation of the peritoneum. Kim Bengochea, Regis University, Denver, Author: While this increase in complexity allows for increase in animal size, it has certain problems. Peritonitis, an inflammation of the peritoneum, results from bacteria entering a perforation in the gastrointestinal tract. Also, take the chance to go further with clinical anatomy of the abdomen by reviewing our clinical case of necrotizing fasciitis of anterior abdominal wall. We guess that your answer comes out of all the hard-to-imagine pouches, layers and sacs. – The pleura is located in the chest cavity, either lining the chest wall (parietal pleura) or covering the lung (visceral pleura), and the peritoneum is the corresponding tissue in the abdomen. Between its two layers – parietal and visceral – is the peritoneal cavity.

Kasper, D. L., Hauser, S. L., Jameson, J. L., et al. Functions of the peritoneum and the greater omentum are: mechanical protection of the anterior abdominal wall. Learning anatomy is a massive undertaking, and we're here to help you pass with flying colours. It maintains homeostasis by allowing exchange of molecules and production of peritoneal fluid, thus providing an environment in which intra-abdominal organs can function properly. All rights reserved. The gastrophrenic ligament, gastrosplenic ligament, gastrocolic ligament and splenorenal ligament form part of the greater omentum. The peritoneum functions to support and protect abdominopelvic organs. The lesser omentum extends superiorly from the lesser curvature of the stomach and proximal duodenum to the liver. The peritoneum tend to be considered a balloon into which the internal organs are hard pressed from outside. New York, NY: McGraw-Hill Education. On a scale from lesser omentum to mesentery, how difficult do anatomy students find the peritoneum? 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. The peritoneum is a membrane made up of two layers. Read more. • So any patient with diagnosed ascites and sudden onset of these symptoms should be examined for peritonitis. Mesothelial cells can…. The peritoneum functions to support and protect abdominopelvic organs. There are two subdivisions of the omentum depending on whether they extend from the greater or lesser curvature of the stomach. So let’s start with the basics; the Peritoneum is a serous membrane which lines the walls of the abdominal cavity and lies on abdominal and pelvic organs. • Harrison’s Principles of Internal Medicine (19th ed.). Depending on how deep the abdominal organs dive into the peritoneum during development, they can be classified as: Intraperitoneal organs are completely wrapped by visceral peritoneum.
The lesser sac communicates with the greater sac via the epiploic foramen (omental foramen) found posterior to the free edge of the lesser omentum. These double layers of peritoneum are the mesentery. Reviewer:
