Quizplus · Accepted Answer

During pregnancy, the mother transfers IgG antibodies to the fetus through the placenta via the umbilical cord. After birth, the mother continues to provide protection by secreting IgA antibodies in the breast milk that are passed on to the baby during nursing. Therefore, the classes of antibodies received respectively are IgG and IgA.
