Yes, the placenta does help protect the fetus from infection. It acts as a barrier, filtering out some harmful substances and pathogens while allowing essential nutrients and oxygen to pass through. The placenta produces various immune factors and antimicrobial proteins that fortify the fetus’s defenses. However, it is not foolproof; certain infections and diseases can still cross this barrier, so prenatal care and maternal health are crucial for additional protection.
