Presentation 10

  1. 1. the reproductive system<br />by Debbie Cornish<br />
  2. 2. gynecology-the study of the female reproductive system<br />
  3. 3. gynecology means "the science of women"  <br />the female reproductive system includes the breasts, uterus, fallopian tubes, ovaries, vagina, and vuvlva.<br />gynecologists perform diagnostic tests such as pap smears (screening test for cervical cancer) and  pelvic exams.<br />
  4. 4. gynecology<br />
  5. 5. ovum (egg)-the female sex cell<br />
  6. 6. ovum<br />
  7. 7. ovum<br />Eggs are produced by the ovaries.  They are the largest cells in the human body.<br />
  8. 8. ovum<br />Eggs contain 23 chromosomes and all contain X chromosomes.  Sperm cells contain either X or Y cells and therefore determine the sex of the fetus.<br />
  9. 9. 3 stages of labor and delivery<br />Dilation stage-Uterine contractions dilate the cervix.<br />Expulsion stage-Birth of the baby.<br />Placenta stage-Delivery of the placenta.<br />
  10. 10. Labor and delivery-dilation<br />The dilation stage occurs from the time true labor begins, until the cervix is completely dilated.  This is the longest stage.  In first time moms this can last 12-16 hours.  For subsequent births it usually lasts around 6-7 hours. There are 3  phases to the dilation stage.<br />Phase 1-early labor.  This is the longest phase with irregular contractions.<br />Phase 2-acive labor.  Here there are regular contractions that become longer and closer together.<br />Phase 3-transition.  This is the shortest but most difficult phase.  The cervix opens and stretches, and the baby descends from the birth canal.<br />
  11. 11. labor and delivery-dilation stage<br />
  12. 12. Labor and delivery-Expulsion stage<br />In this stage the baby is born.  The placenta is cut, and the baby will take its first breath.<br />
  13. 13. labor and delivery<br />
  14. 14. labor and delivery-placental stage<br />This is the shortest stage, lasting 5-15 minutes.  The 3rd stage begins with the birth of the baby and ends with the delivery of the placenta.<br />
