Atthe passage of the oesophagus into the stomach, some 2-3 cm. below the diaphragm,the opaque stratified squamous epithelium of the gullet abruptly changes into the l622 HIMAX ANAT()M\ transparent columnar cells clothing the stomach. The line of transition is zig^zagand well dehned, the oesophageal surface being paler than the highly vascular redgastric mucosa. At the pylorus the mucous membrane is raised into a ring, chiefly Fig. 1372. Ensiforni cartilage VI rib-cartilaRC VIII rib-cartilaxe VII rib-
