(Greek: kolo- > Latin: colo-, colon or large intestine [that part which extends from the cecum to the rectum])
Don't confuse this colo-, col-, "colon, large intestine" unit with the following -cole, -cola, -coles (living among, dwelling in); cole-, coleo- (sheath, scabbard, vagina); coll-, col- (neck); collo-, coll- (glue); and colon-, coln- (farm, settlement) units.
The colon measures about 5 feet (1.5 meters) in length. It goes up (the ascending colon) on the right side of the abdomen, across the abdomen (the transverse colon) beneath the stomach, and then down (the descending colon) on the left side of the abdomen and makes a sharp turn in the left lower portion (the sigmoid colon) to merge with the rectum.
The colon is sometimes inaccurately called the "large intestine" or "large bowel". It is only a part of the large intestine/bowel. The confusion may have arisen because the word colon came from kolon which to the ancient Greeks meant the "large intestine".
