How is o2 blood transferred to the fetus?
i.- i.- i.- O2 enters the i.- i.- i.- i.- i.-i.- i.- i.- i.- i.-



intervillous space via the maternal arteries, to the villi then the
i.- i.- i.- i.- i.- i.- i.- i.- i.- i.- i.-



umbilical vein take the o2 blood to the fetus. The umbilical arteries
i.- i.- i.- i.- i.- i.- i.- i.- i.- i.- i.- i.-



take the deO2 blood from the baby through the villi and back to the

Vasoconstriction


What happens to the spiral arteries during pre-e?
i.- i.- i.- i.- i.- i.- i.- i.-i.- i.- They are i.- i.-



constricted which decreases blood flow i.- i.- i.- i.-




Why does the supine position cause decreased uteroplactenal blood
