Lesser omentum
Greater peritoneal cavity
Gastrosplenic ligament
Lesser sac (omental bursa)
Splenorenal ligament
(Top) The borders of the lesser sac (omental bursa) include the lesser omentum, which conveys the common bile duct and hepatic and gastric vessels. The left borders include the gastrosplenic ligament (with short gastric vessels) and the splenorenal ligament (with splenic vessels).
Greater omentum
Ascending colon
Transverse colon
Small bowel (SB) mesentery
Descending colon
Left paracolic gutter
(Bottom) The paracolic gutters are formed by reflections of peritoneum covering the ascending and descending colon and the lateral abdominal wall. Note the innumerable potential peritoneal recesses lying between the bowel loops and their mesenteric leaves, accounting for the polygonal shape of many interloop or mesenteric fluid collections. The greater omentum covers much of the bowel like an apron.

Hepatogastric ligament
Hepatoduodenal ligament
Epiploic foramen (of Winslow)
Greater omentum
(Top) The lesser omentum comprises the hepatoduodenal and hepatogastric ligaments and forms part of the anterior wall of the lesser sac. The greater and lesser sacs communicate through the epiploic foramen (of Winslow).
Gastrocolic ligament
Transverse colon
