What are the lengths of the different parts of the colon?

The average colon is about 1.5 m long. Lengths of the various parts are:

* Anal canal: 5 cm

* Rectum: 12 cm

* Sigmoid colon: 40 cm

* Descending colon: 15 cm

* Transverse colon: 45 cm

* Ascending colon: 25 cm

The splenic flexure is thus at around 72 cm from the anal verge, and the hepatic flexure at around 117 cm.
