The colon is categorized anatomically into sigmoid colon, descending colon, splenic flexure of the colon, transverse colon, hepatic flexure of the colon, ascending colon, and cecum. The transverse colon is located above the navel and begins on the right side at the hepatic flexure of the colon and ends on the left side at the splenic flexure of the colon. Due to the pulling effect of the mesentery, the transverse colon only moves up and down to a small extent, but will not move to the bottom of the navel, in addition, it can also move left and right to a small extent, before meals and after a full meal the position will not be too big a difference, after a full meal, strenuous exercise can be caused by small bowel torsion. Because the mesentery of the small intestine is relatively long, so the mobility is relatively large, because the mesentery of the transverse colon is relatively short, there will be no transverse colon torsion and movement after a meal, so the transverse colon has been in the upper part of the navel.
