## 1. The female reproductive system

Below you see the female reproductive system

Ovary:
The two ovaries are about the size of a golf ball. The (still) immature eggs are located in the ovary from birth. In girls from about eleven years old, one egg is matured every month.

fallopian tube:
The beginning of the fallopian tube looks a bit like a hand. During ovulation, the egg comes out of the ovary and into the fallopian tube.

uterus:
The fallopian tubes end in the uterus. The uterus is the size of a small fist and is hollow inside. The wall of the uterus consists of muscles on which a mucous layer grows (the endometrium). This mucus layer ensures that the fertilized egg can safely nestle in it. The cavity is connected to the vagina (sheath). A fertilized egg can develop into a baby in the womb.

Urinary bladder:
Bladder in which the urine is temporarily stored. Urine is formed in the kidneys and is also called pee.

Urinary tube:
Tube through which urine leaves the body.

On the outside, a woman has labia, the inner and the outer (small and large), the clitoris, the urethra and the vagina.
The vagina connects the uterus to the outside world. As a result, the child goes outside at birth.

The clitoris is the part of the female genital system that ensures that women get pleasant feelings during sex. There are many nerve endings, making it a very sensitive piece. The clitoris is often depicted as a small dot on the outside, but that's not true at all! The clitoris can be up to 12 cm in size. Just like the penis, the clitoris has erectile tissues.

In girls from puberty

In girls from about eleven years old, one egg matures in the ovaries every month. During ovulation/ovulation, such a mature egg is released from the ovary. The fallopian tubes transport the egg towards the uterus. An unfertilized egg survives for a maximum of 12 to 24 hours after ovulation. After the egg dies, menstruation is initiated. We also recognize this under the name of menstruation. The remnants of the egg are taken up by the cells of the wall of the fallopian tube.

Ovulation occurs about once every four weeks. Usually this happens alternately in one of the two ovaries.
