Vedclass · Answer

(A) The human placenta acts as a selective barrier,but it allows the passage of certain macromolecules from the maternal circulation to the fetal circulation.Specifically,$IgG$ antibodies (a type of globulin) are known to cross the placenta via receptor-mediated endocytosis.This passive immunity provides the fetus with protection against various pathogens.Therefore,the presence of maternal $IgG$ antibodies in fetal blood is direct evidence of the placenta's permeability to these specific macromolecules.

The permeability of the human placenta to macromolecules is evidenced by the presence of which of the following in fetal blood?
