Presentation Transcript

  1. Female Reproductive System Anatomy and Physiology

  2. Female Vocabulary • Ovulation- monthly release of a mature egg from the ovary • Fertilization- union of the ovum (egg) and sperm; when sperm enters egg in fallopian tubes • Menstruation- the shedding of the uterus lining after the ovary releases the egg and the egg is not fertilized.

  3. Vocabulary • Estrogen: the female sex hormone that signals physical changes at puberty and controls maturation of eggs. • Menopause: the time of life which the ovaries slow down their hormone production and no longer release eggs. Age onset around 45-55

  4. Ovulation and Fertilization Fertilization Ovulation

  5. Conception- moment at which the sperm fertilizes the egg

  6. Female Vocabulary • Fallopian Tubes- pair of tubes through which ovum travel, fertilization takes place here • 4-5 inches long, takes egg 7-10 days to travel through • Diameter of 2 strands of hair

  7. 1. Fallopian Tubes

  8. Female Vocabulary • 3. Cilia- hair-like projections which help move the egg through the fallopian tubes ( do not write)

  9. Female Vocabulary • Fimbria- finger-like projections at the end of the fallopian tubes, grab the egg at ovulation and pull it into the fallopian tube

  10. 7. Fimbria

  11. Female Vocabulary • Ovaries- Organ that produces ova or eggs • One egg released every month by alternating ovaries

  12. 8. Ovaries

  13. Female Vocabulary • Ovum- human egg (plural=ova) 23 chromosomes • 500,000 at birth, 500 mature • Unfertilized eggs live about 15-24 hours

  14. Female Vocabulary • Follicle- group of cells released from the ovary, contains ovum. • Progesterone: a hormone that signals changes to a woman's reproductive system during pregnancy.

  15. Female Vocabulary • Uterus- organ that holds and nourishes the unborn baby (Also called womb) • Mucus plug develops during pregnancy, keeps everything in and out until ready for delivery

  16. 2. Uterus

  17. Zygote- 1st trimester of development

  18. Embryo- 2nd trimester of development

  19. Fetus- 3rd trimester of development

  20. Female Vocabulary • Cervix- opening to the uterus, produces fluid to help sperm travel • Cartilage-like material (ex. tip of nose)

  21. 6. Cervix

  22. Female Vocabulary • Vagina- muscular canal that connects the uterus with the outside of the body (Also called birth canal) • About 5 inches long

  23. 5. Vagina

  24. Female Vocabulary • Vulva- external female genetalia = labia minora (small lips) and labia majora (large lips) • Clitoris- small organ at the end of the vulva, purpose is for sexual arousal

  25. 4. Vulva

  26. Additional Terms • Endometriosis: is the abnormal growth of cells (endometrial cells) similar to those that form the inside of the uterus, but in a location outside of the uterus. • Ectopic Pregnancy:An ectopic pregnancy is a pregnancy located outside the inner lining of the uterus. • The Fallopian tubes are the most common locations for an ectopic pregnancy.
