In asthenic states it is low and, because of the lackof tone, the meal settles in the lower pole, allowing the walls of thecardia to collapse. In the prone position the stomach swings upunder the liver, hing more transversely. When empty, its wallsare in apposition except at the cardia which is dilated by thegas bubble. As the stomach fills, the meal collects in a funnel-shaped shadow below the gas bubble and gradually fills out the 158 GASTRO-INTESTINAL TRACT body and antrum. In atonic stomachs the meal passes rapidly tothe lower pole which enlarges out of proportion to the body. The outline is smooth except for indentations due to peristalsis,and a variable amount of irregularity on the greater curvature dueto pressure from the colon and spleen. Small transient indentationsoccur on the margins of the antrum near the pylorus. They aremost common on the lesser curvature and are without significance. KALEVIMA
