Slide 20 - Slide

From pituitary to puberty
First: primary sexual characteristics

Pituitary gland: 
endocrine gland that starts to make puberty hormones (FSH/LH):

girls: around 11
boys: around 13


Slide 21 - Slide

From pituitary to puberty
Puberty hormone (LH/FSH) fits on 
target cells in testes / ovary

testes and ovaries  
are now active!


hormone and  target cell
transport of hormones

Slide 22 - Slide

Ovaries and testes

Women:
ovaries produce
oestrogen and progesterone 

Men:
testes produce 
testosterone


Effect:

Women:
Oestrogen -> bloodstream -> secundairy sexual characteristics

Men
Testosterone -> bloodstream -> secundairy sexual characteristics

Slide 23 - Slide

Milou: hormones are transported through the blood
Rico: hormones pass on signals, because they connect to the cell membrane of certain cells
Who is right?
A
Milou
B
Rico
C
Both
D
Neither
