The Ovaries  The ovary contains specialized cell structures called follicles  A single ovum develops within each follicle  Each month, a follicle matures and ruptures, releasing the ovum into the oviduct  This event is called ovulation  Thread-like projections called fimbraie continually sweep over the ovary  When an ovum is released, it is swept into a cilia-lined tube about 10cm long called an oviduct  The oviduct carries the ovum from the ovary to the uterus  Within the oviduct, the beating cilia create a current that moves the ovum toward the uterus
