Defence mechanisms during pregnancy

CCoPE
Date: 2001-12-21

Question:
How has the human reproductive system evolved to protect the fetus from toxins in the female body? What are the implications of these mechanisms in terms of consuming 'drugs' during gestation?

Answer:
The placenta has some transport mechanisms that can pump out some drugs. But for many dangerous drugs there are no defense mechanisms. For more information please visit this website's section on Pharmacokinetics and Drug Metabolism.
