FETAL PIG LAB ONE: Respiratory 1, Mouth, Pharynx & Thorax External Anatomy Examine the fetal pig and locate the external features shown above. Two rows of nipples of mammary glands are present on the ventral abdominal surface of both males and females. Mammary glands later develop only in maturing females. 1. Determine the sex of your pig by looking for the urogenital opening. On females, this opening is located near the anus. On males, the opening is located near the umbilical cord. If your pig is female, you should also note that urogenital papilla is present near the genital opening. Males do not have urogenital papilla.
