  19. 19. Vulva <ul><li>Protects sexual and urinary organs </li></ul><ul><li>Vulva stretches to accommodate child birth </li></ul>
  20. 20. Labia <ul><li>Are generally the “lips” of the vulva </li></ul>
  21. 21. Skene’s Gland <ul><li>Drains Urethra </li></ul><ul><li>Swells with blood during sexual arousal </li></ul>
  22. 22. Bartholin’s Glands <ul><li>Secrete mucus for lubrication of the vestible </li></ul><ul><li>Sexual stimulation increases mucus production </li></ul>
  23. 23. Vagina <ul><li>This is where the embryo grows into a fetus during pregnancy </li></ul><ul><li>Serves as a “Two way street” </li></ul><ul><li>Area which accepts the penis </li></ul><ul><li>Area where the baby leaves the female </li></ul>
  24. 24. Cervix <ul><li>Directs sperm to uterus during intercourse </li></ul><ul><li>Brings menstrual blood from uterus to the vagina </li></ul>
  25. 25. Uterus <ul><li>Conduit for sperm transport </li></ul><ul><li>Site for implantation of ova </li></ul><ul><li>Placentation (Transfering of food to fetus) </li></ul><ul><li>Growth and development of the fetus </li></ul><ul><li>Parturition (labour and delivery) </li></ul>
  26. 26. Fallopian Tubes <ul><li>A pair (2) of the Fallopian Tubes </li></ul><ul><li>Place where fertillization of the ova happens </li></ul><ul><li>Transports Ova to the uterus </li></ul>
  27. 27. Female Reproductive Cycle Rundown <ul><li>Firstly female produces eggs and readies them for fertilization </li></ul><ul><li>If fertilization occurs, female houses and nourishes the developing embryo until birth </li></ul><ul><li>After birth female feeds baby with milk </li></ul>
  28. 28. Male Reproductive Cycle Rundown <ul><li>Male produces and readies sperm </li></ul><ul><li>Sperm gets released into female and fertilizes ova </li></ul><ul><li>Male provides main source of income to help feed and nourish baby </li></ul><ul><li>(For a while anyways) </li></ul>
  29. 29. Female Hormones <ul><li>Different functions are controlled by hormones </li></ul><ul><li>Changing the hormone concentration in their blood ensures that each of these functions are timed correctly </li></ul><ul><li>Puberty begins at the age of 10 - 14 </li></ul><ul><li>Lutienzing and follicle stimulating hormone start puberty </li></ul><ul><li>They also stimulate production of the estrogen hormone </li></ul>

  37. 37. Erection <ul><li>Male is ready to reproduce or is sexually aroused </li></ul><ul><li>Penis enlarges </li></ul><ul><li>Readies sperm for ejaculating into the vagina </li></ul>
  38. 38. Sexual Intercourse <ul><li>The physical action of sex </li></ul><ul><li>Part where the penis enters the vagina </li></ul><ul><li>Orgasm occures to show that sexual fluids have been successfully released </li></ul><ul><li>Physical part of reproduction </li></ul>
