← Human Body & HealthWhich consequence results when placental apoptotic signaling increases beyond homeostatic limits?
A)Compromised nutrient and waste exchange✓
B)Enhanced fetal immunoglobulin absorption
C)Increased systemic maternal vasodilation
D)Elevated fetal erythropoietin synthesis
💡 Explanation
Increased apoptosis induces syncytial knot formation, impairing the surface area for nutrient and waste transport across the placenta, because it drives cellular self-destruction. Therefore, exchange is compromised, rather than options affecting different physiological pathways.
