How would harmful substances in the mothers blood reach the embryo in her uterus?
Harmful substances in the mother's blood can reach the embryo in her uterus through the placenta. The placenta acts as a barrier between the mother and the embryo, but certain toxic substances can cross this barrier and enter the embryo's bloodstream, potentially causing harm to the developing fetus.
Why is the placenta not an effective barrier against substances that harm the fetus?
The placenta is not an effective barrier against harmful substances because it is designed to facilitate the exchange of nutrients and waste between the mother and fetus. Many toxins, drugs, and infections can cross the placental membrane due to their small size or lipid-soluble nature. Additionally, certain pathogens can exploit mechanisms within the placenta to gain access to the fetal environment. As a result, substances that may harm the fetus can often bypass the protective functions of the placenta.
