THE STOMACH

the genital fold is enlarged, so as to inclose the uterus and a small part of the vagina 

 It forms two extensive folds, the broad Ugaments of the uterus (Ligamenta lata 

 uteri), which attach that organ to the sides of the pelvic cavity and the lumbar 

 part of the abdominal wall (Pig. 530). It thus divides the recto-vesical pouch 

 completely into dorsal and ventral compartments— the recto-genital pouch (Ex- 

 cavatio recto-utennal) and the vesico-genital pouch (Excavatio vesico-uterina) 

 b urther details will be given in the description of the pelvic viscera. 



THE STOMACH 



The stomach (Ventriculus) is the large dilatation of the alimentary canal 

 behind the diaphragm ; it intervenes between the oesophagus and the small intestine. 

 It IS a sharply curved, U-shaped sac, the right part being, however, much shorter

than the left one. The convexity is directed ventrally. When moderately dis- 

 tended, there may be a shght constriction which indicates the division into right 

 and left sacs. It is relatively small, and is situated in the dorsal part of the ab- 

 dominal cavity, behind the diaphragm and hver, mainly to the left of the median 

 plane. 



It presents for description two surfaces, two curvatures, and two extremities. 

 The parietal surface (Fades parietalis) is convex and is directed forward, upward, 

 and toward the left; it lies against the diaphragm and liver. The visceral surface 

 (Facies visceralis), also convex, faces in the opposite direction; it is related to the 

 terminal part of the large colon, the pancreas, the small colon, the small intes-
