THE PERITONEUM 199 



Round anterior border of liver to under surface as far as 

 transverse fissure. 



The two sacs traced horizontally, at the level oj the foramen of 

 Winslow. 



From falciform ligament of liver : 



Over anterior abdominal wall and diaphragm. 



Over outer part of left kidney. 



Reflected outwards behind splenic vessels to spleen, forming 

 posterior layer of lieno-renal ligament. 



Over spleen as far as hilum. 



To stomach, forming anterior layer of gastro-splenic 

 omentum. 



Over anterior wall of stomach into anterior layer of gastro- 

 hepatic omentum. 



Turns round hepatic artery, forming anterior edge of 

 foramen of Winslow (here the smaller sac commences). 



Passing from right to left : 



Forms posterior layer of small omentum. 



Over posterior surface of stomach. 



Forms posterior layer of gastro-splenic omentum, reaching 

 hilum of spleen. 



Forms anterior layer of lieno-renal ligament. 



Passing now from left to right : 



Continues over left kidney, aorta, and inferior vena cava, 

 here forming posterior boundary of foramen of Winslow (here 

 smaller sac ends, and large sac again commences). 



Over right kidney to liver. 



Over under-surface of liver to left border, round which it 

 may be traced over anterior surface, to falciform ligament. 



SYNOPSIS OF PROCESSES OF THE PERITONEUM. 



Omenta folds connected with the stomach. 



Lesser or Gastro-hepatic Omentum. From transverse fissure 

 and fissure for ductus venosus on liver to small curvature of 

 stomach and ist part of duodenum. Right border free, 

 forming anterior boundary of foramen of Winslow. 



Great or Gastro-colic Omentum. Formed, as shown above, 

 by the passing downwards and then folding upwards of the 

 two layers passing from stomach, and thus encloses the lower 

 part of the cavity of the smaller sac of the peritoneum. 



Gastro-splenic Omentum. Passes from fundus of stomach 

 to hilum of spleen, and contains the splenic vessels be- 

 tween its layers. Below it is continuous with the great 

 omentum.
