The Reproductive System

  1. 1. Lesson 3: Human Reproductive System Foundation Science SC 22101
  2. 2. Functions of the Reproductive System Male – to produce sperm and deliver it to female reproductive system. Female – produces eggs and provides a place for an embryo to develop.
  3. 3. Externally Visible Reproductive Organs Penis – male organ that delivers semen to the female reproductive system. Vagina – female organ that receives sperm from the male, also provides a path for baby from uterus to outside world.
  4. 4. Sperm Sperm have 23 chromosomes Sperm is made by the testes The job of sperm is to fertilize the egg…….
  5. 5. What does a Sperm Cell Live for? Egg To fertilize a female egg
  6. 6. Egg Egg has 23 chromosomes also. Eggs are produced by the ovaries.
  7. 7. Functions of Female Reproductive Organs Ovaries make eggs Uterus is where fetus grows into a baby Fallopian tube is where sperm fertilize egg
  8. 8. Functions of Female Reproductive Organs Ovaries make eggs Uterus is where fetus grows into a baby Fallopian tube is where sperm fertilize egg
  9. 9. Developmental Steps: Zygote  Embryo  Fetus 1) Egg is made in the ovary 2) Egg released from ovary and enters fallopian tube 3) Sperm fertilizes egg creating a 46 chromosome zygote 4) Zygote replicates and becomes an embryo 5) Embryo embeds into uterus to become a fetus
  10. 10. 1) Draw and Label Female Reproductive Organs: ovaries, vagin a , cervix, fallopi an tubes, and uterus Questions 2) In the uterus there is an endometrium and a myometrium. “Metrium” means “womb” or “uterus”. DON’T look it up, but guess what an endometrium is. 3) What does “myo” mean in Latin (ask me for help)? Can you now guess what a myometrium is?
