First off, all hormone systems are the same as bulls, so reference that for the beginnings of the female system.
FSH goes to the ovaries, where it stimulates the follicle to become larger, and as it matures, it produces estrogen.
Infundibulum surrounds the ovary, catches the egg, and guides it to the oviduct.
LH (Lut) causes ovulation.
Corpus Luteum - forms where the follicle breaks open (to release the egg) . Produces Progesterone which protects the pregnancy.

Cysterella = GnRH
Lutalyse = Prostaglandin
Lut kills the Corpus Luteum, which in turn, will terminate the pregnancy.
Superovulation - excess FSH is given to produce multiple follicles to in turn, produce more eggs (for flushing)
oviduct - transports the egg and sperm to the site of fertilization, transferred by cilia
Uterus - transports the sperm from the cervix to oviduct, site of embryo implantation, where the calf develops... produces prostaglandin
Vagina and vulva... we know what those are.
Hormones
Estrus - in standing heat, willing to be bred. Due to increased concentrations of estrogen
Estrous Cycle - period of time from one estrus to the next , average of 21 days for cows, 17 for ewes
estrus period - cow 12-18 hours, ewe 24-36 hours
