               Human Female Reproductive System:




               It consists of ovaries, oviduct, uterus, and vagina





               •  Ovaries:  have  two  main  reproductive  functions  in  the



                   body. They produce oocytes (eggs) for fertilization and



                   they produce the reproductive hormones, oestrogen and



                   progesterone.




               •  Uterus: where the embryo develops until birth time



               •  Female  hormones:  progesterone  and  estrogen  are



                   produced from the ovary.



               •  Fertilization:  the  process  of  a




                   sperm joining with an egg to form



                   a  zygote,  it  occurs  in  the  upper



                   portion of an oviduct.







               •  Early development: egg, zygote, morula, blastocyst that




                   is made on the fifth day after fertilization
