  4. Ovaries What is the purpose of the ovaries? • Produces Hormones • Releases eggs • are the size of almonds

  5. Fallopian Tubes What is the purpose of the fallopian tubes? • Transports egg to the uterus • Where fertilization happens

  6. Fallopian Tubes

  7. Ovulation ovary egg fallopian tube

  8. Fertilization happens in the fallopian tubes. sperm egg

  9. Uterus What is the purpose of the uterus? • Where the baby grows • Expands as the baby grows • Muscular tissue that pushes the baby out during labor

  10. Uterus Do you think all animals have a uterus?

  14. Vagina What is the reproductive purpose of the vagina? • Where sperm is deposited • Birth Canal

  15. Egg • Released by the ovaries • Travels down fallopian tube • Can’t swim ( no tail) • Fertilized in fallopian tube • Implants into uterus lining • Size of a pencil dot

  16. Egg

  17. The Male Reproductive System

  18. Testes • Contained in the Scrotum • Within each testis are clusters of hundreds of Seminiforous tubules • Which makesperm • produces testosterone • Need to be kept at a slightly lower temperature

  19. Epididymis • Located on top of the testes • Sperm mature here • Sperm stored here 2-4 days

  20. Vas Deferens 18 inch tube carries sperm from epididymis to urethra

  21. Vas Deferens There are two tubes, one on each side.

  22. Glands • Seminal Vesicle, prostate & bulbourethral • Make seminal fluid which nourishes sperm & protects from acidic female reproductive tract • Sperm + seminal fluid= semen • 50-130 million sperm/mL

  23. Penis • Used to deposit sperm into female

  24. Sperm • Produced in the testes • Mature and stored in the epididymis • Travel through vas deferens to urethra • Ejaculated from urethra • Deposited in vagina • Swim through cervix and uterus • Swim into fallopian tubes to fertilize egg
