Well, even though babies form their “own” blood, the two blood systems do pass oxygen, glucose, CO2, etc. between them.
The sperm and egg unite in one of your fallopian tubes to form a one-celled entity called a zygote. If more than one egg is released and fertilized, you may have multiple zygotes.
The zygote has 46 chromosomes — 23 from you and 23 from the father.
Let’s stop here! Where did these chromosomes come from? Maybe I am overly exited over this miracle, but I just can’t get my mind around how magnificent this is!
I don’t care of PeterJ wants to have a little fun with me over this subject and how I am partially scandalized with the casual tone in your posts over this miracle. But I find this truly fascinating. I’d rather be mocked because I am excited by the conception and incarnation of our Lord than by being skeptic about it, **all **of it. I just can’t get around how special it is for Blessed Virgin Mary to have been impregnated by the Holy Spirit, I mean WOW :angel1:
These chromosomes will help determine your baby’s sex, traits such as eye and hair color, and, to some extent, personality and intelligence.
Soon after fertilization, the zygote travels down the fallopian tube toward the uterus. At the same time, it will begin dividing rapidly to form a cluster of cells resembling a tiny raspberry. The inner group of cells will become the embryo. The outer group of cells will become the membranes that nourish and protect it.
However, during birth, the placenta detaches from the womb and some bleeding occurs. Only at this time can blood from the BABY get into the mother’s blood stream. If the baby has a different blood type than the mother, she will make antibodies to the baby’s blood. So there is usually no problem during the first pregnancy. NEXT time she gets pregnant, if the baby is a different blood type than the mother, the antibodies that she made during the first birth can cross the umbilical cord into the baby (because they are small enough) and hurt the baby. But there are shots that can be given during the first birth that can “suck up” all the baby’s blood cells so that the mother does not make antibodies to them. The only time something could happen to the first baby is if the placenta detaches partially and some bleeding is going on, but not enough to cause miscarriage. This is rare.
At this point, I doubt I can bring anything else for your consideration without you having a counter argument.
I shall go my merry way. Amazed by Christ.
Full of Grace,
The Lord is with thee.
Blessed art thou among women,
and blessed is the fruit
of thy womb, Jesus.
Mother of God,
pray for us sinners now,
and at the hour of death. Amen.
