 the peritoneum simply passes over the liver and diaphragm. 



SPECIAL PARTS OF THE PERITONEUM. After tracing the continuity 

 of the serous sac over the wall and the viscera, the dissector is to 

 study the chief processes or folds of the membrane in connection 

 with the alimentary tube and its appendages. The pieces of peri-

FOLDS CONNECTED WITH THE STOMACH. The processes uniting 

 the stomach to other viscera are named omenta, and are three in 

 number, viz., the small or gastro-hepatic omentum, the large or 

 gastro-colic omentum, and the gastro-splenic omentum. 



The small omentum (figs. 114 and 115, s om} stretches between the 

 liver and stomach, and ends towards the right in a free border, 

 behind which the foramen of Winslow leads into the cavity of the 

 small sac. It is attached above to the liver along the transverse
