The correct answer for the blank is-

uterus.

Explanation:

Fertilized egg (also called zygote) reaches uterus, particularly at blastocyst stage (approximately 5 to 6 days post fertilization) and gets adhered to the uterine wall and from now it is considered as embryo. This process is known as implantation.

During the stage of prenatal development, the growing embryo receives nutrients and oxygen from the mother through placenta and develops into fetus (8th week post fetilization, which is 10th week of pregnancy). Fetus grows within uterus till the last week of pregnancy that is around 38 weeks.

Thus, uterus is the right answer for the given blank.
