the flexures. The first, right venual part (Colon ventrale dextrum), begins at 

 the cseco-cohc orifice about opposite the middle of the last rib, passes downward 

 and forward along the right costal arch, and reaches the floor of the abdomen. 

 Over the xiphoid cartilage it bends sharply to the left and backward, forming the 

 sternal flexure (Flexura diaphragmatica ventralis). The second, left ventral 

 part (Colon ventrale sinistrum), passes backward on the left part of the abdomi-

 forming the pelvic flexure (Flexura pelvina). This is continued by the third, left 

 dorsal part (Colon dorsale sinistrum), which passes forward above the left ventral 

 portion. On reaching the stomach, diaphragm, and left lobe of the liver, it turns 

 to the right, forming the diaphragmatic or gastro-hepatic flexure (Flexura dia- 

 phragmatica dorsalis). The fourth or right dorsal part (Colon dorsale dextrum) 

 passes backward above the first portion, and on reaching the inner or left surface
