Oxygen cannot pass through the placenta
AL2006
The placenta is the structure that allows for transfer of wastes, oxygen, and
nutrients between the mother and the fetus.  The fetal blood comes extremely
close to the maternal blood in the placenta, but there is no intermingling of fetal
and maternal blood.  The fetus and mother can even have, and often do have,
different blood types.
