Here's a breakdown:

* Fertilization: The sperm fertilizes the egg in the fallopian tube.

* Implantation: The fertilized egg (now called a zygote) travels down the fallopian tube and implants itself in the lining of the uterus (the endometrium).

* Embryonic development: The embryo grows and develops within the uterus, receiving nourishment and oxygen through the placenta, which is connected to the embryo via the umbilical cord.
