Which abdominal region contains the right colic (hepatic) flexure?

The right colic (hepatic) flexure is located at the junction where the ascending colon curves to become the transverse colon. This anatomical feature specifically resides in the right upper quadrant of the abdomen, commonly classified within the right lateral lumbar region.

Understanding the division of the abdominal cavity into regions enhances the clarity of anatomical relationships. The right lateral lumbar region is defined as the area on the right side of the abdomen, between the ribs and the iliac crest, encompassing vital structures such as parts of the colon and the kidneys.

The other regions mentioned do not contain the right colic flexure. The left lateral lumbar region is situated on the opposite side and contains different anatomical structures. The epigastric region, located above the umbilical area, primarily houses the stomach and parts of the liver. The right iliac region is characterized mainly by the cecum and appendix. Therefore, the right lateral lumbar region is the correct answer, as it is specifically where the right colic (hepatic) flexure is found.
