where it is separated into two lateral parts by the falciform 

 ligament. The right lateral part of the upper portion 

 extends backwards, between the liver and the diaphragm, to 

 the coronary ligament which separates the upper surface of 

 the right lobe of the liver from the posterior surface (Fig. 

 200) : the left lateral part of the upper end of the sac passes 

 backwards over the upper surface of the left lobe of the liver

to the left triangular ligament. Below the falciform ligament 

 the upper and anterior part of the great sac extends, as a 

 continuous cavity, from side to side, and it projects back- 

 wards, on each side, deeply into the hypochondriac, lumbar, 

 and iliac regions (see Figs. 172 and 173). The back- 

 ward extensions of the great sac form two deep gutters, 

 one on each 'side, in which collections of fluid may become 

 lodged when the body is lying recumbent. The lateral 

 boundary of each of the gutter-like recesses is the lateral
