Final answer:
The bend between the transverse colon and descending colon is called the left colic flexure or splenic flexure.
Step-by-step explanation:
The bend in the colon between the transverse colon and the descending colon is known as the left colic flexure or the splenic flexure. This sharp bend occurs immediately inferior to the spleen.
Food residue, after traversing the transverse colon, reaches this flexure as it moves toward the descending colon. The descending colon then runs down the left side of the posterior abdominal wall. The various parts of the colon, including the transverse and descending sections, are essential in the process of digestion and waste management.
