How does a foetus get its oxygen?
It comes from a temporary organ called the placenta. The fetus is connected to the placenta by the umbilical cord. From the placenta, which is normally attached to the uterine wall, blood, oxygen, and nutrients are transferred through the umbilical cord to the developing fetus.
How long can you carry you baby before they have to induce labor?
They will not induce your labor unless your water breaks or you have a serious health condition anytime before 38 weeks. Usually for a normal pregnancy they will wait until 41 or 42 weeks. If you go any later than that, personally I think you should demand to be induced because you baby is being put at risk staying in there that long. The plancenta begins to deteriorate and the oxygen supply is cut down.
