Fig. 1050. Interior of the Stomach

When examined after death, the stomach is usually fixed at some temporary stage of the digestive process. A common form is that shown in Fig. 1050.

If the organ (viscus) be laid open by a section through the plane of its two curvatures, it is seen to consist of two segments: (a) a large globular portion on the left and (b) a narrow tubular part on the right. These correspond to the clinical subdivisions of fundus and pyloric portions already described, and are separated by a constriction which indents the body and greater curvature, but does not involve the lesser curvature. To the left of the cardiac orifice is the incisura cardiaca: the projection of this notch into the cavity of the stomach increases as the organ distends, and has been supposed to act as a valve preventing regurgitation into the esophagus.

In the pyloric portion are seen: (a) the elevation corresponding to the incisura angularis, and (b) the circular projection from the duodenopyloric constriction which forms the pyloric valve; the separation of the pyloric antrum from the rest of the pyloric part is scarcely indicated.
