Slide 5 - Tekstslide

fact

Girls carry all egg cells since birth in their ovaries
normally 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

Next: Take out your notebook!
1. Read the information (and watch the video using earphones) on the next slides and take notes. 
2. You will have to answer questions about the topic afterwards.

Slide 7 - Tekstslide

What is menstruation?
  • Release of blood from the uterus (uterus lining) through the vagina
  • Start around age 12
Take notes in your notebook!

Slide 8 - Tekstslide

Slide 9 - Video

How does it happen? 
  • Hormones estrogen en progesterone build up uterus lining

  • Fertilized egg could attach to this

  • No fertilized egg? --> Lining is shed

  • cylce: it happens over and over again (450 times in a life time)
Take notes in your notebook!

Slide 10 - Tekstslide

The menstrual cycle

Slide 11 - Tekstslide

4 Phases
  • Phase 1 (day 1-5) : menstruation
    Uterus lining is shed through the vagina (no fertilized egg)

  • Phase 2 (day 6-12): repair phase
    uterus lining build new layer of mucus
    *new egg cell develops in the ovary

Slide 12 - Tekstslide

4 Phases
  • Phase 3: Ovulation (day 13-15)
    A new egg cell (ova) is released and send down the oviduct (fallopian tube)

  • Phase 4: Receptive phase (day 16 - 28)
    Uterus lining grows to form a 'nest' for the egg cell
    *No fertilized egg cell? --> cycle starts again!
