Describe the pathway oocytes take to reach the uterus. Describe the structure and function of the uterus.
Oocytes normally enter the large, funnel-shaped ends of the oviducts or Fallopian tubes that surround but are not continuous with the ovaries. The action of cilia that line the upper ends of the oviducts help guide oocytes into the tubes. The other ends of the oviducts enter into the upper end of the uterus. The size of a fist, the uterus lies behind the bladder in the lower abdominal cavity. The uterus has thick muscular walls, a mucous lining in which fertilized eggs embed themselves, and many blood vessels which contribute to the formation of the placenta.
