Female reproductive system
Fertilization usually happens in the fallopian tubes. This is the beginning of embryogenesis. The fertilized egg will then go through many divisions to form a blastocyst. The blastocyst which sticks itself in the wall of the uterus. This is the start of gestation. The baby will continue to grow until full-term. When the  baby has grown enough, the cervix opens and contractions of the uterus propel the newborn through the birth canal (the vagina).
