  1. 1. FEMALE REPRODUCTIVE SYSTEM PReSENTED BY :- Ms. ROMENA BEGUM 1st YEAR MSC (N)
  2. 2. Introduction •The reproductive organs in female are concerned with copulation,fertilization,growth and development of the fetus and child birth.
  3. 3. Functions of Female reproductive system 1. Oogenesis 2. Copulation 3. Hormone production
  4. 4. 4.Menstruation
  5. 5. 5. Provide sites for Egg Fertilization Implantation Development.
  6. 6. Female Reproductive System 1.External genital organs. 2.Internal genital organs. 3.Accessory reproductive organs.
  7. 7. External genitalia 1.Mons pubis. 2.Labia majora. 3.Labia minora 4.clitoris. 5.Hymen . 6.Vestibular gland.
  8. 8. Internal organs • Vagina • Uterus • Two fallopian tubes • Two ovaries
  9. 9. Vagina It is an elastic fibro-muscular tube and membranous tissue about 8 to 10 cm long.
  10. 10. To allow discharge of the menstrual flow. Functions of vagina
  11. 11. •As the female organs of coitus. Functions of vagina
  12. 12. •To allow passage of the fetus from the uterus. Functions of vagina
  13. 13. •The uterus is a hollow, pear shaped muscular organ. Uterus
  14. 14. •The uterus measures about 7.5cm long , 5cm wide, 2.5 cm thick and weight about 30 – 40 gm. Uterus
  15. 15. I.Fundus II. Body III. Cervix Parts of uterus
  16. 16. Layers of uterus Perimetrium Myometrium Endometrium
  17. 17. Functions of uterus Menstruation -Process of shedding the lining of the uterus.
  18. 18. Menstrual Period •If the ovum is not fertilized it doesn’t attach to the endometrium. •Muscles of the uterus contract  lining breaks down (“cramps”) •Lining passes through the cervix into the vagina and out of the vaginal opening
  19. 19. Pregnancy -the uterus support and allows the fetus to grow. Functions of uterus
  20. 20. Labor and birth-the uterine muscles contract and the cervix dilates during labor . Functions of uterus
  21. 21. FALLOPIAN TUBES •The Fallopian tubes, also known as, uterine tubes, and salpinges , are two very fine tubes. •Length 10 to 11 .5 cm long. •Its divided into 4 parts.
  22. 22. Parts : 1) Interstitial part 2)Isthmus 3) Ampulla 4)Infundibulum
  23. 23. 1) Interstitial :It is 1.25 cm long and lies within the wall of the uterus. 2)Isthmus :Upper outer angle ,its narrow part of the tube,about 2-3 cm in length . 3) Ampulla :Middle portion,its wider part about 5 cm in length.fertilization occurs in the ampulla. PARTS OF FALLOPIAN TUBES
  24. 24. 4) Infundibulum :Terminal portion , its funnel shaped. The infundibulum ends in finger like projection called fimbriae. PARTS OF FALLOPIAN TUBES
  25. 25. Functions Gamete transport (ovum and sperm). Fertilization Transport of fertilized and unfertilized ovum to the uterus.
  26. 26. OVARY •The ovaries are almond shaped gland,placed on each side of the uterus. •They are 2.5 to 3.5 cm long-2 cm wide,1 cm thick.
  27. 27. Structure of the ovary •Germinal epithelium • Tunica albuginea • Medulla • Ovarian follicles • Mature graffian follicle • corpus luteum
  28. 28. Functions of ovary 1)They produce oocytes (eggs) for fertilization . 2) They produce hormones, oestrogen and progesterone. 3)Ovulation.
  29. 29. Accessory reproductive organs Breast : Breast is a mass of glandular, fatty and connective tissue.
  30. 30. Structure of the Breast •Lobules • Lactiferous Duct • Fatty and connective tissue •Areola •Nipple
  31. 31. The breast is made up of: •Lobules – glands that produce milk.Each breast has 15 to 20 lobes •Ducts – Tubes that carry milk from the lobules to the nipple.
  32. 32. •Fatty and connective tissue – Surrounds and protects the ducts and lobules . •Areola – Circular area around the nipple . •Nipple – Centre of the areola,the nipple contains about 15 to 20 lactiferous ducts.
  33. 33. Function of the breast • Lactation
  34. 34. Summary Structure and function of the • External genitalia • Internal genitalia Vagina Uterus Ovaries Fallopian tubes Structure and of breast.
