Where and how does normal fertilization and implantation occur?

Fertilisation occurs in the fallopian tube (aka oviduct/ uterine tube). Implantation occurs in the uterus (aka womb).
If the zygote (fetilised egg) were to implant itself away from the uterus, it would be classified as an ectopic pregnancy and the potential mother would have to go through an abortion or she would die. The only environment suitable for a zygote to develop into a fetus and then a baby is the uterus, no where else.
The zygote will then go through a series of mitotic divisions called cleavage. It will then form a morula, then a blastocyst (still floating in the uterus). Its zona pellucida will break down to form the inner cell mass which is surrounded by trophoblast. The trophoblast would then expose itself to adhesive molecule that will allow it to implant into the endometrial wall tissue of the uterus. The trophoblast will secrete digestive enzymes to borrow itself into the tissue. It will differentiate to cytotrohoblast and syncitiotrophoblast (outer). The syncitiotrophoblast will destroy cells and the trophoblast will use the nutrients and oxygen to begin placental formation.
The chances of this happening is small because 2/3 of all zygotes do not implant itself into the uterus and spontaneously abort.
