What are the three urogenital openings for in rats?

In rats, the three urogenital openings serve distinct functions: the urethral opening, which is used for the excretion of urine; the vaginal opening in females, which is part of the reproductive system for mating and birthing; and the anal opening, which is for the excretion of feces. These openings are crucial for waste elimination and reproductive processes in both male and female rats.
