  • 1. Our Body Systems
  • 2. Why do we need to reproduce? • To ensure survival of the species • To produce egg and sperm cells • To transport and sustain these cells • To nurture the developing offspring • To produce hormones
  • 3. Male Reproductive System
  • 4. Male Testes - produce sperm - also known as testicles and gonads
  • 5. Male Duct System Vas Deferens - transports mature sperm to the urethra Epididymis - sperm mature in epididymis
  • 6. Male Seminal vesicles – attached to vas deferens – produce a sugar- rich fluid that provides energy to sperm
  • 7. Male Prostate Gland – makes fluid
  • 8. Male Urethra – tube that carries urine from the bladder to outside of the body – also carries sperm out of the body
  • 9. Male
  • 10. REVIEW: The Journey of the Sperm (4) (3) (7) (5) (6) (2) (1)

  • 20. Amnion - transparent sac that protects the baby inside - filled with amniotic fluid
  • 21. Sperm Egg Cell
  • 22. 6 weeks umbilical cord
  • 23. 8 weeks placenta
