All animals need to reproduce to keep their kind going. But how does it happen in us, humans?
The reproductive system is responsible for the creation of new life.
Humans have sexual reproduction. This means that a male and female come
together to form a new baby.
The reproductive system includes the organs that work together for the purpose of reproduction.
As we grow up, our body starts to change and our reproductive organs develop.
Men and women have different reproductive systems.
These two reproductive systems need to work together so that we can reproduce.

THE MALE REPRODUCTIVE SYSTEM.
The male reproductive organs are on the inside and the outside of the body.
The testicles store and produce sperm. The testicles are locates in a bag called scrotum.
The penis is connected to the testicles by small tubes.

The urethra is a tube in the penis.
Sperm travels through the urethra to the outside of the body.

THE FEMALE REPRODUCTIVE SYSTEM.
The female reproductive organs are mostly inside the body.
The ovaries store and produce eggs.
The uterus is connected to the ovaries by tubes.
The vagina is a muscular tube and connects the uterus to the outside of the body.
The vulva is on the outside of the body and covers the opening of the vagina.
HOW WE BORN??
Reproduction begins with fertilisation and ends with birth. A human pregnancy lasts nine months. The umbilical cord transports nutrients from the mother to the foetus.
1. Fertilisation: a sperm joins an egg.
In the first three months…
2. The embryo is about the size of a small seed.
3. The embryo becomes a foetus. The foetus is about the size of a bean.
4. Limbs start to grow and organs start to develop.
In the second three months…
5. The face starts to form.
6. The foetus has all its organs and it continues to grow.
In the last three months…
7. The foetus is developed and preparing to be born.
Birth
8. The baby leaves the uterus and is born.
