Bible Question:
It was said in this post that the blood of the mother never enters the blood stream of the fetus. Is that verifiable in a biology text somewhere? I find the speculation fascinating. I will not be surprised to discover it is true. After all the Lord told the Jews thousands of years ago to circumcize their sons on the 8th day, and it is only recent medical research that has verified that the baby's blood clotting factors are not up to full working capacity until the 8th day. I would really like a source to verify this biological assertation about "the bloodstream of the fetus", please. Thank you, Melanie |
Bible Answer: Melanie, greetings. I found the following, which I hope helps ... During pregnancy, fetal blood cells are made in the fetus. The fetal RBCs have the characteristics that are inherited from his/her parents. The mother continues to maintain her own separate blood supply with its own unique characteristics. The placenta acts as a barrier between the blood systems of the mother and her baby and passes oxygen and other nutrients from the mother's blood to that of the child while maintaining the blood supplies separately.
