The regulation of placental function and blood supply plays a crucial role in ensuring the optimal growth and development of the fetus. Understanding this intricate process provides valuable insights into prenatal physiology. To illustrate, let us consider a hypothetical scenario where maternal hypertension affects placental blood flow.
One important aspect of regulating placental function is maintaining an appropriate balance between vasoconstriction and vasodilation within the uteroplacental circulation. In cases of maternal hypertension, excessive vasoconstriction may occur, leading to decreased blood flow to the placenta. This reduction in perfusion can compromise oxygen and nutrient delivery to the developing fetus, potentially resulting in intrauterine growth restriction (IUGR) or other adverse outcomes.
Several factors contribute to the regulation of placental blood supply:
- Nitric oxide (NO): A potent vasodilator produced by both maternal vascular endothelium and trophoblast cells.
