wall of the abdomen, formed superiorly by the diaphragm, 

 which separates the peritoneal gutters from the lower parts 

 of the pleural sacs, and inferiorly by the flat muscles of the 

 abdomen. The medial wall of the right gutter is formed by 

 the right kidney and the ascending colon (see Figs. 173 

 and 174), and the medial wall of the left gutter by the

The dissector should pass his hand from above down- 

 wards along each of these lateral gutters of the anterior part 

 of the great sac and he will find that each is divided by a 

 transverse fold of the peritoneal wall into an upper and a 

 lower part, but the division occurs at very different levels on 

 the opposite sides. On the left side the fold which separates 

 the upper from the lower part of the left gutter is the 

 phrenico-colic ligament, which lies at the level of the eleventh
