Gestation refers to the time between when a baby is conceived till the baby is delivered. This is why the period of pregnancy is known as the <em>Gestation Period. </em>
During that time and after the fertilized egg implants itself in the uterus, the baby develops and grows until it is ready to be delivered.
The structure this occurs in is the uterus (womb) which is labelled 9 in the structure above.
