Ascending colon (Colon ascendens)
Educational content only — not medical advice.
Anatomy
The second large-bowel segment, a retroperitoneal fixed ascent from caecum to the hepatic flexure joining the transverse colon; supplied by the right colic artery (SMA). Its final water absorption and colonic bacterial vitamin K/biotin production occur here.
Clinical notes
Rarely herniated through the lumbar triangle; its referred pain projects to the right abdomen, and its cancer (with the caecum) is the classic site of chronic colonic anaemia.
