FORAMEN OP WINSLOW. 557 



The folds, formed between these and between the diaphragm and 

 the liver, are 



(Diaphragm.) 



Broad, coronary, and lateral ligaments. 



(Liver.) 

 Lesser omentum. 



(Stomach.) 



Greater omentum. 



(Transverse colon.) 



Transverse meso-colon, 



Mesentery, 

 Meso- rectum, 

 Recto-vesical fold, 

 False ligaments of the bladder. 



And in the female, the 



Broad ligaments of the uterus. 



The ligaments of the liver will be examined with that organ. 

 The Lesser omentum is the duplicature passing between the liver 

 and the upper border of the stomach. It is extremely thin, excepting 

 at its right border, where it is free, and contains between its layers, 

 the 



Hepatic artery, 



Ductus communis choledochus, 



Portal vein, 



Hepatic plexus of nerves, 



Lymphatics. 



These structures are enclosed in a loose areolar tissue, called 

 Glissorfs capsule.* The relative position of the three vessels is, the 

 artery to the left, the duct to the right, and the vein between and 

 behind. 



If the finger be introduced behind this right border of the lesser 

 omentum, it will be situated in an opening called the foramen of 

 Winslow.^ In front of the finger will lie the right border of the 

 lesser omentum ; behind it the diaphragm, covered by the ascending or 

 posterior layer of the peritoneum ; beloiu, the hepatic artery, curving 

 forwards from the cceliac axis ; and above, the lobus Spigelii. These, 

 therefore, are the boundaries of the foramen of Winslow, which is no- 

 thing more than a constriction of the general cavity of the peritoneum
