What are the three functions of the cloaca aperture?

The cloaca aperture serves three primary functions: it acts as the exit point for digestive waste, allowing for the expulsion of feces; it facilitates the elimination of urinary waste by providing an outlet for urine; and it plays a role in reproduction by serving as the passage for eggs or sperm during mating in certain species. This multifunctional structure is essential for the overall excretory and reproductive processes in animals that possess it.
