All openings of the body that led to the outside are moist with mucus. This includes the mouth and the rest of the digestive tract, the respiratory tract (including the nasal passages), the urinary tract and the reproductive tract. This mucus keeps the tracts from drying out. If they would dry out, microbes could get into the body and cause an infection. The mucus also produces easy passage of products into and out of them.

Fertilization occurs in the oviduct of the female reproductive tract
The lower end of female reproductive tract in pigs is not very different from humans. The reproductive system is conserved across all mammals.
1-5 days
It is called the vulva, which is literally the opening of the vaginal tract.
It is called the cloaca The male chicken does not have a penis and there is no penetration of the female reproductive tract at the time of mating. Instead the female inverts her cloaca which comes in contact with the male's inverted cloaca and receives the sperm. The cloaca is then drawn back into the hen's body and the sperm are captured. They then begin the journey up the length of the reproductive system. The sperm live inside the female reproductive system for up to 10 days and each time an ovulation occurs (every 24-26 hours in good egg producers) the egg can become fertile.
Slightly acidic, all the time, I believe.
