Epididymis: Temporary storage for sperm cells.
Sperm duct: Transports the sperm cells.

Slide 8 - Tekstslide
external female reproductive system
External part of the female reproductive system is called the vulva.
Clitoris: is the pleasure center of the vulva.
Inner labia: Glands in the inner labia produce mucus during sexual arousal. This lubricates the entrance of the vagina so the penis can slide in easier.

Ovulation

Ovulation = when a ripe egg cell is released by the ovary
Happens every 4 weeks
One week left ovary, other week right ovary
Egg cell lives 24 hours
Slide 11 - Tekstslide
Slide 12 - Video

Menstruation
When an egg is not fertilised, part of the uterus lining detaches. This is called menstruation.
Average age for girls to start their menstruation is 13.
Slide 14 - Tekstslide
Slide 15 - Video
