mass called zygote. This little zygote takes three to four days to reach
the warm and cozy environs of the uterus. All these significant
developments will be carried out within the first two weeks and this
process lays the foundation for the creation of a beautiful baby.

and the uterus. This is often called the lifeline for the undeveloped
