It is called foetal oxygen; the embryo is transformed to foetus in six week time. During this period stem cell (the connecting tube from endometrium to the embryo on the endometrium) has to form and oxygen carrying blood has to flow from the endometrium to embryo, now the sack formation (heart formation) start. If oxygen carrying blood is not pumped to the embryo this lead to growth retardation, low heart beat and lead to abortion.
