Peritoneal Features
The parietal and visceral peritonea are continuous with one another at double folds of serosa called mesenteries (see above). in some locations, visceral peritoneum reflects off one region of the gut, spans a short distance, then merges onto the surface of nearby structures.
Although these double folds of peritoneum are typically very thin, in this configuration they are sometimes referred to as ligaments. Some examples include the falciform ligament, which tethers the liver to the ventral midline; the renosplenic (nephrosplenic) ligament, spanning between the left kidney and spleen; and the hepatoduodenal ligament, connecting the liver and proximal duodenum.Omentum refers to those parts of the peritoneum connecting the stomach with other structures. it is divided into a lesser omentum, extending from the lesser curvature of the stomach to the liver, and the greater omentum, which is attached to the greater curvature of the stomach (and the comparable portion of the ruminant stomach). The greater omentum spreads like an apron from the stomach to cover most of the ventral aspect of the mass of intestine.
