The cloaca is the distal extension of which gut region?

Explanation:
The cloaca represents the distal end of the hindgut. In embryology, the gut is divided into foregut, midgut, and hindgut, with the hindgut extending from the distal transverse colon down to the anorectal region. The cloaca is the terminal chamber of the hindgut that later partitions to form the anorectal canal and parts of the urinary and genital systems. Foregut and midgut do not reach this region, so they are not correct extensions.
