Stages of life
During life, the body goes through several changes. Some of these changes have to do with sex hormones

Slide 5 - Slide

Secondary sexual characteristics
  • When the child reaches puberty, sex hormones are produced to develop the secondary sexual characteristics. 
  • These are processes and structures that develop throughout puberty. When someone has developed everything, they have reached the end of puberty
  • Examples: menstruation, facial hair, lower voice, ...

Slide 14 - Drag question

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

Slide 15 - Open question

The reproductive system
Contains all the organs needed for an organism to be able to sexually reproduce. This system is regulated by hormones.

Slide 16 - Slide

Hormones
= regulatory substances that control processes in the body
  • They do that by giving signals to organs (messengers)
  • Produced by hormone glands from the endocrine system
  • Transported by the circulatory system to get them where they need to be
  • Effect can have a duration of hours up until months/years
Dutch for glands = klieren
Messengers
Hormones are messengers. However, that was the task of the nervous system, right? The difference: the nervous system is for the fast messages (to help you feel and move), the hormones are for the slower messages (to help you grow and change). 

Slide 17 - Slide

Regulation of reproductive system by hormones

The regulatory system is regulated by hormones. Mostly oesterogen (in females) and testosteron (in men). The release of these hormones is controlled by the pituitary gland. During early pregnancy the women also produce progesteron to prepare for the implantation of the embryo in the mucous membranes.
implantation = innesteling

mucous membranes = baarmoederslijmvlies
This is not discussed in the book, but still very important to know!

Slide 18 - Slide

GONADS

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

Slide 19 - Slide

Sex hormones
  • Hormones that work in the reproductive system are called sex hormones
  • Some of those are different for males and females
  • Production of these leads to the differences between male and female bodies
  • This production happens in many stages of life!

Slide 20 - Slide

GONADS

  • The pituitary gland sends hormones to the gonads 
  • And then the gonads produce more hormones to get the reproductive processes going

Slide 21 - Slide

GONADS
Which ones are the male and female gonads?

  • Male = testis
  • Female = Ovary

Slide 22 - Slide

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)

Slide 23 - Slide

Put in your wordlist!
  • 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)

Slide 24 - Slide
