A fertilized ovum, (the females egg), develops into a blastocyst, an embryo, then a fetus. If a sperm penetrates the egg, fertilization happens. The fertilized egg (zygote) im â¦ plants into the uterus. The cells of the zygote divide repeatedly as the zygote moves down the fallopian tube. The zygote then takes 3 to 5 days to enter the uterus. In the uterus, the cells continue dividing, becoming a hollow ball of cells called a blastocyst.
Embryo implantation in humans. After fertilization the human embryo begins a 4 day long journey down the fallopian tube and into the uterus. When the embryo reaches the blastocyst stage it develops two distinct populations of cells. The outer cell mass,called the trophectoderm, and the inner cell mass. There is also a fluid filled cavity - as seen in the picture below.
