<P> When an oocyte is developing in an ovary , it is encapsulated in a spherical collection of cells known as an ovarian follicle . Just prior to ovulation the primary oocyte completes meiosis I to form the first polar body and a secondary oocyte which is arrested in metaphase of meiosis II . This secondary oocyte is then ovulated . The follicle and the ovary 's wall rupture , allowing the secondary oocyte to escape . The secondary oocyte is caught by the fimbriated end and travels to the ampulla of the uterine tube where typically the sperm are met and fertilization occurs ; meiosis II is promptly completed . The fertilized ovum , now a zygote , travels towards the uterus aided by activity of tubal cilia and activity of the tubal muscle . The early embryo requires critical development in the Fallopian tube . After about five days the new embryo enters the uterine cavity and on about the sixth day implants on the wall of the uterus . </P>
