title: Control of pulmonary vascular resistance in the fetus and newborn.
abstract: This article describes the anatomy and physiology of the fetal, transitional, and neonatal circulations and then reviews our current state of knowledge about the many factors that work in concert to govern pulmonary vascular resistance.
