  14. Menstruation (Having periods)

  15. Menstruation Estrogen and progesterone prepare the lining of the uterus for pregnancy If pregnancy does not occur, this lining is shed (removed) Lining made up of blood & tissue Passes from uterus through cervix & vagina to outside of body Tampons (inserted in vagina) & sanitary pads (attached on underwear) absorb blood & tissue Process repeats about once a month to create this new lining If pregnancy occurs (the fertilized egg implants in the uterine lining), a period does not occur
