Question

Quizplus · Accepted Answer

To protect the child against infectious agents both in utero and during the first few postnatal months, a system of active transport facilitates the passage of maternal antibodies into the fetal circulation. The antibodies are transmitted via the placenta and are related to the mother's immune system. The infant's own IgG-related antibodies reach protective levels by 6 months of age. The antibodies are not transferred via the lymphatic system, are not directly related to maternal nutrition, or reach protective levels after 6 months of age.
