  1. The female reproductive system matures at puberty and enables women to reproduce.

  2. fallopian tubes • vagina • menstruation • cervix • eggs • ovaries • uterus • ovulation

  3. Female Reproductive Organs • The organs of the female reproductive system enable pregnancy to occur with the first monthly ovulation. • The female reproductive system matures at puberty.

  4. Female Reproductive Organs • The female reproductive system has several functions, including producing female sex hormones and storing the eggs. Eggs or Ova Female gametes (reproductive cells)

  5. Female Reproductive Organs • A female at birth has more than 400,000 immature ova in her ovaries. Ovaries The female sex glands that store the ova, or eggs, and produce female sex hormones. Born with 400,000+ immature ova.

  6. Female Reproductive Organs • The ovaries are located on each side of the uterus. Uterus The hollow, muscular, pear-shaped organ that nourishes and protects a fertilized ovum until birth

  7. Female Reproductive Organs • The process of ovulation is controlled by the release of luteinizing hormone by the pituitary gland. Ovulation The process of releasing a mature ovum into the fallopian tube each month

  8. Female Reproductive Organs • A mature ovum is released from an ovary and moves into one of the two fallopian tubes. Fallopian tubes A pair of tubes with fingerlike projections that draw in the ovum

  9. Female Reproductive Organs Cervix The cervix is the opening of the uterus. The uterus protects and nourishes a developing fetus. Uterus The ovaries contain ova and produce hormones. Ovaries Ova travel to the uterus through the fallopian tubes. Fallopian Tubes Endometrium Thickened lining of the uterus. The passageway from the uterus to the outside of the body. Vagina

  10. Female Reproductive Organs • Sperm from the male enter the female reproductive system through the vagina. Vagina A muscular, elastic passageway that extends from the uterus to the outside of the body

  11. The Anatomy of the Female Reproductive System

  13. Female Reproductive Organs • The fertilization of an egg by a sperm produces a cell called a zygote. • When the zygote leaves the fallopian tube, it enters the uterus and attaches itself to the uterine wall. The fetus remains in the uterus until birth.

  14. Female Reproductive Organs • After a female matures, the uterus prepares each month for possible pregnancy. If pregnancy doesn’t occur, menstruationoccurs. Menstruation The shedding of the uterine lining

  15. Female Reproductive Organs • The endometrium tissues pass through the cervix and into the vagina. Cervix The opening to the uterus

  16. PITUITARY HORMONES Follicle Stimulating Hormone (FSH):  stimulates ovary to produce estrogen, which triggers an ovum (egg cell) to mature Luteinizing Hormone (LH):  stimulates ovary to produce progesterone  responsible for ovulation

  17. Menstruation ~ 28 day cycle • Cycle starts with the 1st day of the menstruation • Days 1-8 • Endometrium breaks down into blood, tissues and fluid and flow out of the vagina. • “periods” usually last 4-8 days, varies

  18. Menstruation • Days 9-13 • The hormones FSH & LH signal: - an egg to mature - the uterus to get ready to receive a new egg: the lining (endometrium) starts to thicken, and blood & nutrients flow into the uterus to protect the fertilized egg (zygote)

  19. Menstruation • Days 14-21 • Ovulation occurs – Mature egg is released from the ovary and travels down fallopian tube • Just before ovulation, cervix releases “mucous” which helps the sperm move towards the egg. • If egg is not met with a sperm cell than the egg begins to dissolve.

  20. Menstruation • Days 21-28 • Egg travels through the fallopian tube to the uterus. • If the egg is not fertilized than the uterus no longer needs the extra blood & nutrients. • A change in hormone levels signals the blood vessels to cut off the blood supply. • The blood dissolves and leaves the body through the vagina as the next cycle begins (Day 1).

  21. Female Reproductive Organs Let’s look at the cycle http://womenshealth.gov/faq/menstruation.cfm http://kidshealth.org/misc/movie/bodybasics/bodybasics_female_repro.html

  22. Maintaining Reproductive Health • Good hygiene, breast self-exams, and abstinence from sexual activity help female reproductive system health. • Sound health practices will help females care for their reproductive systems.

  23. Maintaining Reproductive Health • Tips for Maintaining Your Reproductive Health • Bathe regularly. • Have regular medical exams. • Practice abstinence.

  24. Breast Self-Exam • Breast cancer is the most common cancer and the second leading cause of death, after lung cancer, for women in the United States.

  25. Normal AnatomyCancerous Cell

  26. Breast Self-Exam • The American Cancer Society recommends that females examine their breasts once a month, right after the menstrual period, when breasts are not tender. • Early detection is critical for successful treatment of breast cancer.

  27. Female Reproductive System Problems • Several disorders can affect the female reproductive system, and some can lead to infertility. • While menstrual cramps and premenstrual syndrome are common, toxic shock syndrome is uncommon.

  28. Female Reproductive System Problems Menstrual Cramps Cramps that occur at the beginning of a menstrual period Premenstrual Syndrome A disorder caused by hormonal changes Toxic Shock Syndrome A rare but serious bacterial infection that affects the immune system and the liver

  29. Infertility and Other Disorders Infertility in females can have several causes. Endometriosis Uterine tissue grows outside the uterus STDs Diseases spread through sexual contact Infection that causes discharge, odor, pain, itching, or burning Vaginitis Ovarian cysts Fluid-filled sacs on the ovary Cancer Cancer of the cervix, uterus, or ovaries

  30. Cervical Cancer

  31. After You ReadReviewing Facts and Vocabulary • What is the function of the uterus? • The uterus protects and nourishes a developing fetus.

  32. After You ReadReviewing Facts and Vocabulary • Distinguish between ova, ovaries, and ovulation. • The ova are egg cells. The ovaries are the female sex glands that store the ova and produce female sex hormones. Ovulation is the process of releasing a mature ovum into a fallopian tube each month.

  33. After You ReadReviewing Facts and Vocabulary • Identify a kind of cancer of the female reproductive system that is linked to a sexually transmitted disease (STD). • Cervical cancer
