ABDOMEN 



It receives food through the oesophagus or gullet, which 

 opens into the stomach at the upper end of the lesser curva- 

 ture, below and to the right of the fundus, whilst at its lower, 

 and right or pyloric extremity, it becomes continuous with 

 the duodenum, which is the first part of the small intestine. 



The fundus is full and rounded, and forms a marked 

 bulging directed upwards and backwards. It occupies the 

 back part of the left cupola of the diaphragm, from which 

 it is partially separated by the spleen and the liver. 



FIG. 142. The Stomach has been removed from its bed so as to display 

 the recess in which it lies. 



The aisophageal or cardiac orifice is situated to the right of 

 the fundus and about 50 mm. (two inches) below its summit. 

 It lies at the upper end of the lesser curvature, but in certain 

 conditions appears to be partly on the upper surface. 



The pylorus, or narrow right extremity of the stomach, is, 

 as a rule, directed backwards. It is continuous with the 

 duodenum or commencement of the small intestine, the line 

 of junction being marked, on the surface, by a slight but 

 obvious constriction, termed the diiodeno-pyloric constriction. 



The two surfaces of the stomach, as a general rule, look 

 for the most part upwards and downwards. The upper surface 

 is fuller and more convex than the lower surface, It is
