The ascendingcolon extends up-wards and back-wards and reachesnearly to the liver,where the hepatic flexure forms a more or less acute angle. The hepatic flexure, together with the first portion of the transversecolon, is frequently ptosed, drawn forwards and downwards ; but this con-dition need not necessarily give rise to Fig. 309. -Opaque food in the intestines of a child, showing irregulai-position of colon. 364 EADIOGRAPHY The transverse colon extends from the hepatic flexure to the splenicflexure. It varies greatly in position, frequently forming a well-marked loopreaching down into the pelvis. The ascending and transverse colons maybe entirely in juxtaposition when the latter is ptosed, adhesions sometimesbinding the two together. The transverse colon forms a tense band aroundthe greater curvature of the stomach, the latter third of the transverse colonrising almost perpendicularly to the splenic flexure, where it forms an acuteangle with the descending colon. It is often difficult to differentiate the one from the other bythe ordinary radio-graph. Stereoscopicradiographs areuseful when doubtexists as to the con-dition present. The splenic flexureis firmly held up tothe diaphragm by astrong ileo-colicligament. The descendingcolon extends fromthe splenic flexu
