THE STOMACH 415 
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 ligaments 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 (Fig. 530). It thus divides the recto-vesical pouch 
completely into dorsal and ventral compartments—the recto-genital pouch (Ex- 
cavatio recto-uterina) and the vesico-genital pouch (Excavatio vesico-uterina). 
Further 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 cesophagus 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 slight 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 liver, mainly to the left of the median 
plane. 
It presents for description two surfaces, two curvatures, and two extremities. 
he parietal surface (Facies parietalis) is convex and is directed forward, upward, 
d 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 
rminal part of the large colon, the pancreas, the small colon, the small intes-
