Welcome to this lesson!

Today we will check what you learned from paragraph 2.2, and we will move on to paragraph 2.3.

Goals

• You can name the parts of the male reproductive system a sperm cell moves through from formation until ejaculation
• You can name all parts of the female reproductive system and what their functions are

First..

A few questions about paragraph 2.2, to check if you've understood it!

Which of the following is NOT a male reproductive organ?

1. Seminiferous tubules
2. Pituitary gland
3. Prostate
4. Vas deferens

Can you explain what the function of the prostate is?

Because of prostate enlargement due to aging (bigger prostate), men can have issues with urinating. Explain why this happens

Put the organs in the correct order a sperm cell travels, from sperm production until ejaculation: Epididymus, Prostate, Sperm duct, Testis, Urethra

GONADS

During the videos of the male reproductive system, you might have noticed a certain word being used that we did not discuss:

the gonad (plural: gonads). 

• Gonad = reproductive gland, which is the gland that produces the gametes and sex hormones of an organism

GONADS

But wait.. Wasn't that the pituitary gland?

• Yes, and no. 
• The pituitary gland sends hormones to the gonads 
• And then the gonads produce more hormones to get the reproductive processes going

GONADS

Which ones are the male and female gonads?

• Male = testis
• Female = Ovary

THEN WHAT ARE GAMETES?

Gonad = reproductive gland, which is the gland that produces the gametes and sex hormones of an organism

• Gamete = 'sex cell', the cell that is produced to perform the fertilisation and thus the reproduction
• Male gamete = sperm
• Female gamete = egg (oocyte, ovum)

Drag to check if you understood!

GONAD

GAMETE

Sex cell

Sperm

Egg

Ovary

Gland that produces hormones and gametes

Testis

To summarize..

• Gonad = reproductive gland, which is the gland that produces the gametes and sex hormones of an organism
• Activated by the hormones of the pituitary gland
• Male gonad = testes; Female gonad = ovary

• Gamete = 'sex cell', the cell that is produced to perform the fertilisation and thus the reproduction
• Male gamete = sperm; Female gamete = egg (oocyte, ovum)

And now towards 2.3..

The female reproductive system

What do you already know?

What parts of the female reproductive system do you already know? Name them!

The female reproductive system

• External (outside the body, visible): vulva, labia, clitoris 
• Internal (inside the body, not visible): everything else

• Note: normally, we call the 'outside part' the vagina. However, this is actually not true. The vagina is part of the inside organs. The correct term for the 'outside' would be vulva.

VIDEOS

• The following slides both contain videos about the anatomy of the female reproductive system
• You can choose one to watch 
• The longer one is more specific, but very complete
• The shorter one is missing a few parts, which you then have to figure out for yourself in the book

That was it!

• Next lesson, we will quiz you to check if you understand the different parts of the female reproductive system
• To prepare yourself for that, we have the same assignment as last time for you in itslearning: submit a list of all the bolded words in the paragraph, together with their definition. Deadline = before the next lesson (Friday)

Homework

• The assignment as noted in the last slide
• Make exercise 7-10 in your workbook
• Go through paragraph 2.1, 2.2 and 2.3, and see if there's anything you didn't understand.

Any other questions/remarks for your teacher?
