Editing Peritoneum (section)

===Subdivisions===
[[Mesentery#Peritoneal folds|Peritoneal folds]] are omentums, mesenteries and [[ligament]]s; they connect organs to each other or to the abdominal wall.<ref name="Drake2009p295">{{cite book|last1=Drake|first1=R. L.|last2=Vogl|first2=A.W.|last3=Mitchell|first3=A.W.|chapter=Abdominal Viscera|chapter-url=https://books.google.com/books?id=_ozrqnzzhFwC&dq=These%20folds&pg=PA295|page=295|title=Gray's Anatomy for Students|date=4 April 2009|publisher=[[Elsevier Health Sciences]]|location=Philadelphia, PA|isbn=9781437720556|oclc=489070574}}</ref> There are two main regions of the peritoneal cavity, connected by the [[omental foramen]].
* The [[greater sac]], represented in red in the diagrams above.
* The [[lesser sac]], represented in blue. The lesser sac is divided into two "omenta":
** The [[lesser omentum]] (or ''hepatogastric'') is attached to the [[lesser curvature of the stomach]] and the [[liver]].<ref name="Tortora">{{cite book | vauthors = Tortora GJ, Anagnostakos NP |title=Principles of anatomy and physiology |date=1984 |publisher=Harper & Row |location=New York |isbn=978-0-06-046656-5 |edition=4th}}</ref>
** The [[greater omentum]] (or ''gastrocolic'') hangs from the [[greater curvature of the stomach]] and loops down in front of the [[intestines]] before curving back upwards to attach to the transverse [[colon (anatomy)|colon]].<ref name="Tortora" /> In effect it is draped in front of the intestines like an apron and may serve as an insulating or protective layer.<ref name="Tortora" />

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:
