What is the peritoneum? What is it divided into?
- Serrous membran w/ parietal and visceral layers
- serrous fluid in between
(like lungs & heart)
- Divided into LESSER & GREATER sac
What sac (lesser or greater) forms the omental bursa?
LESSER Sac
- forms lesser and greater omentum
Once you open the peritoneum in a cadaver, are you in the greater or lesser Sac?
GREATER Sac
- accounts for most of the space of the peritoneal cavity
Is the lesser or greater sac inside the greater omentum?
Lesser Sac
- behind the stomach
The lesser sac is a closed cavity in females. True or False.
FALSE
- open cavity for fallopian tube to open into peritoneal cavity

Ventral mesentery only at UMBILICUS
- Dorsal mesentary suspends the GUT
The ventral mesentery becomes what ligament?
Falciform Ligament of the Liver
What are the names of the peritoneal folds in the following structures:

SAD PUCKER
