Welcome to this lesson!

Now, we will check what you learned from paragraph 2.1, and we will move on to paragraph 2.2.

Goals

• You can name all parts of the male reproductive system and what their functions are
• You can name the external and internal parts of the male reproductive system

But first..

A few questions about paragraph 2.1, to check if you've understood it!

Can you explain what the function of a hormone is?

What is the difference between primary and secondary sexual characteristics?

Which of the following is NOT a secondary sexual characteristic?

1. Menstruation
2. Pubic hair
3. Sex hormones
4. Muscle growth

And now towards 2.2..

The male reproductive system

Many words regarding the male system are already known, some more decent than others .. ;)

Time for 'het vieze woorden spel'!

Name all the names for parts of the male reproductive organs that you know!

The male reproductive system

Biological words we use:

• Penis
• Testis 
• Scrotum

The male reproductive system

• External (outside the body, visible): penis and scrotum 
• Internal (inside the body, not visible): everything else

Why are penis and scrotum outside?

The male reproductive system

• External (outside the body, visible): penis and scrotum 
• Internal (inside the body, not visible): everything else

Why are penis and scrotum outside?

• Scrotum: For production of healthy sperm cells, a temperature lower than the body temperature is required.
• Penis: For injection of sperm into female reproductive organs

VIDEOS

• The following slides both contain videos about the anatomy of the male reproductive system
• You can choose one to watch 
• The longer one is more specific, but very complete (skip 7:00-13:00)
• 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 male reproductive system
• To prepare yourself for that, we have an assignment for you: make a list of all the bolded words in the paragraph, together with their definition. Deadline = before the next lesson.

Homework

• The assignment as noted in the last slide
• Make exercise 4-6 in your workbook
• Prepare for paragraph 2.3 (read through it, look up the words you don't know, etc)

Any other questions/remarks for your teacher?
