Which part of the large intestine is involved at the hepatic flexure?

The hepatic flexure, also known as the right colic flexure, marks the transition point between the ascending colon and the transverse colon. This anatomical landmark is located in the upper right abdomen where the ascending colon bends to become the transverse colon. Therefore, the part of the large intestine directly involved at the hepatic flexure is the ascending colon, as it leads into the transverse colon at this junction.

The other parts of the colon are not directly involved at this specific junction. The transverse colon continues beyond the hepatic flexure, while the descending colon starts after the transverse colon bends at the splenic flexure. The rectum, being a terminal part of the digestive tract, is located much further down and is not connected to the hepatic flexure at all. Understanding these specific anatomical relationships helps clarify why the ascending colon is the correct part associated with the hepatic flexure.
