The function of the cervix in fetal pigs is to carry their unborn. This allows for a litter rather than just being able to carry just one.
If you had a hysterectomy due to cervical cancer or pap-related problems, you would still have pap smears of the vaginal cuff, even if you didn't have a cervix. If you had your uterus and cervix removed for other reasons, such as bleeding or fibroids, you can stop pap smears, but should continue annual GYN exams.
