The fetal circulation is an entirely transient event, not replicated at any point in later life, and functionally distinct from the pediatric and adult circulations. Understanding the physiology of the fetal circulation is vital for accurate interpretation of hemodynamic assessments in utero, but also for management of circulatory compromise in premature infants, who begin extrauterine life before the fetal circulation has finished its maturation. The cardiovascular system develops early in the embryonic stage of development. It starts towards the end of the third week or at the beginning of the fourth week of fetal development. Once the cardiovascular system is fully established, blood circulation commences and the embryo can directly derive nutrients from its own blood supply. In this paper we analyze some data about the characteristics of the maternal-fetal circulation, which have not been elucidated if we start from the fact that our body takes oxygen from the air that surrounds it. We also comment on the differences when we take into account the hitherto unknown capacity of human eukaryotic cells to oxygenate themselves, from the dissociation of intracellular water molecules, as in plants.
