the retro-peritoneal connective tissue and by the peritoneal reflections. The shape 

 allows the food from the stomach as well as the fluid poured into it from the liver 

 and pancreas to accumulate and thus to act as an S-trap to prevent the passage of 

 gases from the intestine into the stomach. At the same time the great development 

 of the plicae tends to retard the passage of the food. 



Peritoneal Relations. The peritoneum of the front and back of the stomach 

 is continued along the right and left sides of the first part of the duodenum respec-

 the lenerofnentum, which ends posteriorly, as already stated, by forming the hepatico- 

 duodenaj ligament, consisting of the vessels entering the portal fissure of the liver 

 with their enveloping connecti\e tissue. The free edge where the peritoneum passes 

 behind the ligament is on the inner side rather than above the gut. Just back of this
