After the nurse describes fetal circulation to a pregnant woman, the woman asks why her fetus has a different circulation pattern than hers. In planning a response, the nurse is guided by the principle that:
 
  A) Fetal blood is thicker than that of adults and needs different pathways
  B) Fetal circulation carries highly oxygenated blood to vital areas first
  C) Fetal blood has a higher oxygen saturation and circulates slower
  D) Fetal heart rates are rapid and circulation time is double that of adults

Response:
Fetal circulation functions to carry highly oxygenated blood to vital areas first while shunting it away from less important ones. Fetal blood is not thicker than that of adults. Large volumes of oxygenated blood are not needed because the placenta essentially takes over the functions of the lung and liver during fetal life. Although fetal heart rates normally range from 120 to 160 beats per minute, circulation time is not doubled.
