Question

Where does the fertilized cell (egg) attach itself for the remainder of the
pregnancy?

Answer 1

The fertilized egg attaches itself, to the wall of the uterus and implants itself into the uterine lining.

Answer 2

A fertilized egg, or zygote, takes about five days to reach the uterus from the uterine tube. As it moves, the zygote divides and develops into a blastocyst, with an inner mass of cells and a protective outer ring. The blastocyst attaches to the wall of the uterus and gradually implants itself into the uterine lining.
