What is the lesser sac?
The omental bursa or lesser sac is a hollow space that is formed by the greater and lesser omentum and its adjacent organs. It communicates with the greater sac via the epiploic foramen of winslow, which is known as the general cavity of the abdomen that sits within the peritoneum, but outside the lesser sac.

What is the Supracolic compartment?
The supracolic compartment contains the liver, spleen, stomach, and lesser omentum. The infracolic compartment contains the coils of the small bowel surrounded by the ascending, transverse, and descending colon and the paracolic gutters.
What are the Mesenteries quizlet?
A type of connecting peritoneum between the intestinal and reproductive tracts to the abdominal wall. They are the expansive, double-layered serosal folds between the visceral peritoneum and the parietal peritoneum. They contain the blood vessels, lymphatics and veres supplying their respective organs.
