Take notes in your notebook!
Slide 8 - Tekstslide
Slide 9 - Video
How does it happen?

Fertilized egg could attach to this

cylce: it happens over and over again (450 times in a life time)

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!
