Respiration in the Fetal-Placental Unit

  • Robert W. Rothstein

Abstract

Development of the embryo, fetus, and neonate requires appropriate respiratory exchange of oxygen and carbon dioxide. During intrauterine life, the placenta serves as the lung for the fetus, permitting respiratory gas exchange and regulating acid-base balance. In this and many other ways, the placenta fulfills the functions of a variety of organs essential to extrauterine existence. With birth, physiologically one of the most tumultuous events of life, the responsibility for respiratory function shifts from the placenta to the neonatal lung, which must change within a matter of seconds from a relatively passive structure with fluid-filled airways to an active member with relatively full functional capacity.
