How does the site of urethral emptying in the female pig differ from its termination in a human?

In female pigs, the urethra empties into the vaginal vestibule, which is located near the vulva. In contrast, in humans, the urethra exits separately from the vaginal canal, opening directly to the external urethral orifice located anterior to the vaginal opening. This anatomical difference reflects variations in reproductive and urinary system structures between the two species.
