Ovulation

This image shows the process of ovulation. The ovary contains hundreds of immature ovarian follicles, which mature once a month resulting in the ovulation of a mature oocyte. The fanned ends of the Fallopian tube act to catch and guide the ovulated oocyte down the Fallopian tube, which if met with a spermatid undergoes fertilisation and progresses into the uterus where it will implant in its rich endometrial lining. It the oocyte is not fertilized it will pass in to the uterus and be removed when the endometrial lining sheds during menstruation.
