The embryo gets all the oxygen, and all the nutrients that it needs from the mother's blood supply, all of which crosses the placenta, through the umbilical cord into the embryonic blood system.
The umbilical vein carries oxygenated blood away from the placenta and delivers it to the fetus. Oxygenated blood is essential for the baby's growth and development during pregnancy.
The fetus is supplied with oxygen and nutrients through the placenta, which is connected to the mother's uterine wall. The mother's blood passes through the placenta, allowing oxygen and nutrients to pass from the mother's bloodstream to the fetus. Waste products from the fetus also pass through the placenta into the mother's bloodstream for elimination.

IgG is the only antibody small enough to cross he placenta.
IgG is an immunoglobluin monomer, meaning that it is one immunoglobulin that is small enough to cross the placenta. An example would be the Rh antibody that causes isoimmunization between Rh negative mothers and Rh positive fetuses. In constrast, ABO blood group immunoglobulins are IgM which is a pentamer, meaning it is composed of 5 immunoglobulins and is too large to cross the placenta.
