Repeat Basic 2   A woman 

the female reproductive system

Internal female reproductive system

1. Vagina: Where penis enters, where baby exits.

2. Uterus: Place where baby develops.

3. Fallopian tube: carrie egg cells (ovum) to the uterus. 

4. Ovary: Develops ova (sex cells). 

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. 

Uterus (baarmoeder)

Fallopian tube (eileider)

Ovary (eierstok)

Urinary bladder (blaas)

Urethra (urinebuis)

Vagina

Where does fertilisation take place?

1. Ovary
2. Fallopian tube

2. Fallopian tube

• Ovulation in Dutch = eisprong
• Ovulation = when a ripe egg cell is released by the ovary

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.

The menstrual cycle

• After the menstruation the uterus linings starts to grow thicker again and have more blood vessels.
  

•  Ovulation starts +- around 14 days after the start of the last menstruation.

• Next menstruation starts about 28 days after the start of the last one.

Egg cells survive for 1 day,
Sperm cells about 2 to 3 days in the uterus.

What days are the fertile period
(vruchtbare periode) for the woman?
