Study Notes
Placental Functions
- Oxygen from maternal blood crosses the placental barrier to the fetus, while carbon dioxide from the fetus crosses back to maternal blood
- The placenta facilitates nutrient exchange:
- Carbohydrates, fats, proteins, amino acids, vitamins, and minerals from maternal blood are transferred to the fetus
- Waste products, such as urea and uric acid, are removed from the fetus through the placenta to maternal blood
Immunological Protection
- The placenta permits the passage of IgG antibodies from maternal blood to fetal blood, providing passive immunity
- It prevents most microorganisms and drugs from passing from maternal blood to fetal blood
Important Exceptions
- Certain pathogens, such as poliomyelitis, AIDS, syphilis, and measles, can cross the placental barrier and cause congenital anomalies
- A few drugs can also cross the barrier, resulting in fetal harm
