Nonamiya [84]

The fertilized egg enters a 2-week period of cell division. during this period, the fertilized egg is known as an embryo.

Following sexual intercourse, sperms move from the vagina via the cervix and uterus to the fallopian tubes, where only a single sperm fuses with the egg.

The fertilized egg or the zygote divides constantly as it travels down the fallopian tube to the uterus. Initially, the zygote is transformed into a solid ball of cells after which it changes into a hollow ball of cells i.e. a blastocyst.

The blastocyst gets embedded in the wall of the uterus, where it evolves into an embryo connected to a placenta and enclosed by fluid-filled membranes.
