After today you can...

 ... explain wat function hormones have

... describe the physical and emotional changes during puberty

Concepts: 
Hormones, testosterone, oestrogen, Pituitary gland, secondary sexual characteristics, physical changes, emotional changes, development process.

Puberty

= the period in which you develop into an adult

• Physcial changes = secundary sex charasteristics 
• Emotional changes 

CLIL choice

Of de A-Z lijst of de venn diagram 

In pairs:
Make a list from A - Z related to puberty
Indicate if this is related to male, female or both

Let's compare

• Draw to circles, similar to the picture on the right. 
• Left circle is male, right circle is female middle part is both male and female
• Write down changes of puberty in the right space

Hormones are responsible for changes

• In the brain the pituitary gland (hypofyse klier) produces hormones
• Hormones are transported in the blood stream 
• At the place of change tissue react 
• Sex hormones are testosteron for male and oestrogen for female

Everyone is different

Everyone develops at their own pace

After today you can...

- explain how sperm cells and egg cells are formed

- describe the menstrual cycle

Concepts: 

Sperm cells, epididymides, seminal vesicles, prostate gland, semen, egg cells, ovulation, endometrium, embryo, menstruation, menstruation cycle, menopause, sanitary pads, menstruation underwear, tampon, menstrual cup.

Remember?

• Route of sperm cells:
  testis -> epididymis -> sperm duct -> urethra 
• Seminal vesicle and prostate add fluid  

Remember last lesson

• Each month an eggs ripe in the ovary
• A ripe egg enters the fallopian tube = ovulation
• An egg cell meets a sperm cell in the fallopian tube = fertilization 

Period

Menstruation

Loss of endometrium (baarmoederslijmvlies) and blood trough the vagina 
NO EGGS

fact

fake

Girls carry all egg cells since birth in their ovaries

all healthy women have a menstrual cycle

the menstruation blood contains an egg cell 

the length of the menstrual cycle differs per individual

the average age for the first menstruation is 11 years

Menstrual cycle

1. Menstruation

2. follicle phase (eggs cell ripen) 

3. Ovulation

4. luteal phase (build up of endometrium)

Menstruation

Loss of endometrium (baarmoederslijmvlies) and blood trough the vagina 
NO EGGS

Follicle phase (2)

• Phase 2: Follicle phase (day 6-12)
• A new egg cell develops in the ovary
• Egg cell is surrounded by a follicle 
• Start grow endometrium 

Ovulation (phase 3)

• 1 or 2 egg cell(s) is released from the follicle 
•  The egg cell is released and send down the fallopian tube
• Egg cell survives 24 hours 
•  Egg 
  

4 phases

• Phase 4 luteal phase: the body prepairs for pregnancy
•  Endometrium (uterus lining) grows to make a "nest" for the fertilized egg
• No fertilization? Menstruation starts again

What determines the beginning of the menstruation cycle?

1. Release of blood through the vagina
2. The release of the egg cell from the ovaries
3. The growing of the uterus lining
4. The cycle can start anytime

In which part of the female reproductive system do the ova (egg cells) develop?

1. Fallopian tube/Oviduct
2. Ovaries
3. Uterus
4. Vagina

In which part of the female reproductive system does the fertilised egg cell grow into a baby?

1. Fallopian tube/Oviduct
2. Ovaries
3. Uterus
4. Vagina

On which day in the cycle does ovulation occur?

1. Day 1
2. Day 14
3. Day 20
4. Day 28

What is shed during the menstruation of a female?

1. The ovaries
2. The egg cell
3. The uterus lining
4. Nothing

2. False
