And once this process takes place, known as fertilization we form the zygote. So as soon as we form that zygote that zygote begins to move along the cilia along the cilia of the fallopian tube and towards the uterine cavity. And eventually, as it moves along the fallopian tube it begins a process known as cleavage. Now, once it reaches the cavity of the uterus it undergoes a process known as blastulation to form a blastocyst. And about seven days after fertilization took place that blastocyst will implant itself onto the endometrium onto the lining of the uterus of that individual woman. And once implantation takes place, we begin to form the placenta.
