 of the liver to the right costal arch and examine the stomach. 



Ventriculus. The stomach is a pear-shaped organ which 

 lies in the left hypochondriac and epigastric regions, partly 

 below and partly to the left side of the liver. Its long 

 axis runs obliquely and is curved upon itself, the base or 

 fundus of the organ being situated above, behind, and to 

 the left, whilst the apex or pylorus lies lower, more anteriorly,

and more to the right. Traced from its highest to its lowest 

 point, it runs first forwards and slightly downwards, then to 

 the right, and finally slightly backwards to its junction with 

 the duodenum or proximal portion of the small intestine. 

 When the left lobe of the liver is pulled upwards and to the 

 right the oesophagus will be found entering the stomach, a 

 little to the right of the highest point of the fundus, at the 

 cardiac or oesophageal orifice. From that point the two borders 

 of the stomach can be traced to the pyloric end of the organ. 

 The upper border or lesser curvature is much the shorter ; it 

 runs downwards and to the right in a fairly uniform curve. 

 The greater curvature is much longer. First it ascends from the 

 oesophagus to the highest point of the fundus. After crossing
