  1. reproductive systems can be divided into the internal reproductive organs and the external genitalia. The gonads are the actual organs that produce the gametes. In the male, testes produce sperm, and in the female, ovaries make eggs. Reproductive system

  2. Female Reproductive System • Functions- • Reproduction • Production of Eggs - through ovulation • Production of female sex hormone - oestrogen - Progesterone - Estrogen

  3. Structures • Ovaries • female gonad, in which the ova and the hormones that regulate female secondary sex characteristics develop. • Follicles • one of the small ovarian sacs containing an immature ovum. • Egg • Female sex cell • Oocyte • developing egg

  4. Structures cont. • Uterine tubes • Moves the ova from the ovaries to the uterus. • Uterus • Female organ where the fetus develops. • Vagina • The passage leading from the uterus to the vulva or birth canal.

  5. Estrogen • Produced by ovarian follicles • Main female sex hormone • Stimulates growth of uterus and vagina • Egg maturation • Menstruation

  6. Male Reproductive System • Functions- • produce sperm in testes • reproduce • production of sex hormones • testosterone

  7. structures • Testes • Male gonad produces sperm • Scrotum • Pouch of skin surrounding the testes • Sperm • Male sex cells • Seminiforoustubules • Coiled duct within the testes that make and transport sperm

  8. Structures cont. • Epididymis • Coiled tubes near the testes where sperm mature • Vas deferens • Tube that connects the epididymis to the urethra • Seminal vesicle • Sac at the base of the vas deferens that adds to the seminal fluid • Prostate gland • Gland at base of bladder that adds to the seminal fluid

  9. Structures cont. cont. • Interstitial cell • Secretes hormones between testes • Urethra • Tube that carries both urine and semen • Cowper’s gland • Small organs near the prostate that add to the seminal fluid • Penis • Male excretory and copulatory organ

  10. Testosterone • Male sex hormone • Develops sex organs • Sperm production • Secondary sexual Characteristics • Facial hair • Deep voice • Baldness can also result from testosterone production
