..is the foreign body in the mother’s womb. Why doesn’t mother’s body rejects it then?
Re: Fetus
Someone rejected it over the weekend and left it in the trashcan.

Read the question again 
Re: Fetus
I did. Ok another answer would be that it does reject it, but after a few months.
Re: Fetus
EMM, did you learn about hemolytic disease of newborns? (Rh disease)
thats not it but thats the most hilarious answer Re: Fetus
becuase the fetus is in embronicfluid, thus the mother’s antibodies..something like the blood supply doesnt mix 
…we talked abt it in class…hmm cant remmber 
Allah mad it so!

If you are looking for serious answer.
It is not foreign body . The egg which is fertilized by papa's sperm and becomes fetus is created by mothers own body, so it is 100 percent indigenous to her body, isn't it ?
Re: Fetus
To put it simply, there are tissues that make up the blood-placental barrier, which keep the mother's blood from mixing with the fetus's blood in order to prevent an immune response...while allowing for the exchange of nutrients, oxygen, and waste products. Antibodies, which can mediate an immune response, can cross the placenta (this is important, as it will allows the baby to have a competent immune system when it is born)...and this is the reason why it is in fact possible under certain circumstances for there to be an immune response against fetal tissues (as in hemolytic disease of the newborn).
There is ongoing research to explain the matter further; some immunologists believe that the fetus secretes enzymes that suppress the maternal immune response to fetal tissues...

That would only be true if every child was 100% genetically identical to his/her mother, which simply isn't the case. 50% of the fetuses genes come from the father, so its inevitable that the fetus will express proteins that the mother does not; which, barring the natural defenses that I mentioned in my previous post, would cause an immune response similar to what you would get in an organ transplant.

Re: Fetus
Scientists have long believed that the developing fetus avoids destruction due to a maternal protective mechanism that somehow makes the womb safe. But the new findings indicate that the fetus actually creates its own protected site. It does this by secreting the enzyme idoleamine 2,3-dioxygenase (IDO), which counters any assaults from the mother’s immune system by destroying the amino acid tryptophan. Tryptophan is the fuel I-cells require to initiate their attack on foreign tissues.
Re: Fetus
well we should do some research on it
