PLATE VII. REGIONS OF THE ABDOMEN AND THEIR CONTENTS (EDGE OP COSTAL 

 CARTILAGES IN DOTTED OUTLINE). 



For convenience of description the abdomen may be artificially divided into nine 

 regions by drawing two circular lines round the body parallel with the cartilages of 

 the ninth ribs, and the highest point of the crests of the ilia ; and two vertical lines

 The viscera contained in these different regions are as follows :
