The term left colon is hypernymous to descending colon in precise use; ... with descending/sigmoid colon (at right) measuring on average 6.3 cm (range 6.0-6.8 cm). [1]
Since the average length of the human colon is 160.5 cm [11] and the average inner circumference of the colon is 6.2 cm, [34] the inner surface epithelial area of the human colon has an average area of about 995 cm 2, which includes 9,950,000 (close to 10 million) crypts.
The length of the human colon is, on average 160.5 cm (measured from the bottom of the cecum to the colorectal junction) with a range of 80 cm to 313 cm. [11] The average inner circumference of the colon is 6.2 cm. [10] Thus, the inner surface epithelial area of the human colon has an area, on average, of about 995 cm 2, which includes ...

The sigmoid colon (or pelvic colon) is the part of the large intestine that is closest to the rectum and anus. It forms a loop that averages about 35–40 centimetres (14–16 in) in length. It forms a loop that averages about 35–40 centimetres (14–16 in) in length.
It crosses the abdomen from the ascending colon at the right colic flexure (hepatic flexure) with a downward convexity to the descending colon where it curves sharply on itself beneath the lower end of the spleen forming the left colic flexure (splenic flexure). In its course, it describes an arch, the concavity of which is directed backward ...
Unlike other portions of the colon, the rectum does not have distinct taeniae coli. [6] The taeniae blend with one another in the sigmoid colon five centimeters above the rectum, becoming a singular longitudinal muscle that surrounds the rectum on all sides for its entire length. [7] [6]
