Is this a sow or a gilt? How do you know the difference?

Gilt: Has a smaller reproductive tract and the ovaries have less structures present on them
What is the function of the Vulva?
- Passageway for urine
- Receptor for penis during copulation
- Passageway for fetus during birth
- Protection - prevents material from environment from entering tract
What are the functions the the Epididymis?
