what happens after the fertilisation of male and female gametes in humans

After fertilization zygote is formed. Zygote divides repeatedly and forms embryo. This embryo is attached on the wall of uterus and it grows. Cell specification starts and they make group to develop as different organs of body. When all the body parts are in condition to be identified, embryo is called as foetus. After the completion of development of foetus a baby's birth takes place.
