Anatomy study note · Abdomen
Ascending colon
About 13 cm long, it runs up the right side from the caecum to the underside of the liver, where it bends as the right colic (hepatic) flexure. It is retroperitoneal, covered by peritoneum in front and at the sides.
Key points
- Caecum → hepatic flexure; retroperitoneal.
- Ileocolic + right colic arteries (SMA).
- Lies on the right kidney lower pole.
- Post-arterial midgut; becomes retroperitoneal.
- Colon: no villi, many goblet cells.
- Outer longitudinal muscle → teniae coli → haustra.
