6. Take out a sheet of scratch paper
Engage:
Take out a sheet of scratch paper
(You can tear from the back of your notebook)
Silently write down all of the nicknames you have heard for the human sexual organs.

7. NOW BALL IT UP AND THROW IT IN THE TRASH!
We will not be using these words any more. This is biology, and in science we use words like…
Penis
Vagina
Uterus
Say them three times fast and giggle if you need to. After this slide you will be mature young adults.
Line garbage cans up in the middle of the room for this activity

8. Let’s take awkward notes…
Take out a clean sheet of paper and set it up like this

Vocabulary Word Notes

9. Male Anatomy The journey of a sperm…

10. It all begins in the testis…
Vocab Notes MALE ANATOMY Testis paired organs, make sperm. Scrotum Houses testis, located outside the body because they need to be cooler

11. Sperm
Head contains the DNA, mid-piece which has mitochondria (why?) and a tail (flagella) which allow them to swim.

12. Once the sperm mature…
They move to the epididymis where sperm is stored.
Eventually the sperm will travel out the vas deferens which is a tube that transport sperm to prostate gland.

13. Sperm Release
Seminal vesicle: gland that secretes mucous-like fluid into vas deferens
Prostate gland: secretes a fluid to assist the movement of semen

14. Male Reproductive System
Penis- Organ which inserts into female to deliver semen
Urethra: tube that transports sperm out of body, also transports urine

15. You should have notes for 9 structures in the male reproductive system

16. Female Anatomy: The Journey of an egg

17. It all begins in the Ovaries…
Vocab Notes
FEMALE ANATOMY
Ovary paired organs, make and store eggs.
Ovum Egg (about (Ova) 400,000 are housed in the ovaries)

18. Movin’ on out… Ovulation process where 1 egg exits ovaries (1/month)
Fallopian Tunnel like Tubes structure that (Oviduct) transports ova to uterus
*Site of Fertilization

19. Female Anatomy Uterus Cervix Vagina Houses developing embryo
Muscle which seperates uterus from vagina
Vagina
Receives penis during intercourse

20. You should have notes on 7 structures for the female reproductive system

21. Stay tuned for what happens when a sperm and egg finally meet!
Take the next 10 minutes to label your diagram on Page 32 according to the notes we’ve just taken

23. Steps of Human Development
Fertilization: The process of a sperm joining an egg.
After the 2 haploid nuclei fuse, a single diploid cell is formed called a zygote.

24. Steps of Human Development
Zygote divides: zygote → blastocyst → embryo
This was once you!

25. 6 days later…
Implantation Blastocyst forms and implants inside of the uterus

26. Later Development

27. Mother Child Connection
The developing baby is connected to the mother by the placenta and by the umbilical cord. These are the baby’s source of oxygen, nourishment and excretion.
