Descrizione:
The zygote ends up in the uterus. While this is happening, the zygote begins to split into a cluster of cells. This is called a morula. As it rapidly divides into more cells, it becomes known as a blastocyst and implants itself into the endometrium, or uterine lining. The inner cells in the blastocyst will become the embryo, and the outer cells will become the placenta.
