Which substance is transferred across the placenta and provides a newborn with temporary passive immunity?
Correct answer: A. Maternal IgG antibody
- A. Maternal IgG antibody
- B. Newborn IgM antibody
- C. Maternal platelet factor
- D. Newborn T-cell memory
Explanation
Maternal IgG crosses the placenta and protects the newborn temporarily after birth. This is passive immunity because the infant receives ready-made antibodies rather than producing them through its own immune response.
