Is a pregnant mother’s blood kept separate from her fetus’ blood?

Question

I have searched online multiple times to see whether a pregnant mother’s blood and her fetus’ blood are kept separate. I’ve even looked in textbooks, and often it’s implied but never said outright and plainly in those terms.

I’ve looked online, but I’ve not yet found a reputable source that spells it out clearly.

Are a pregnant mother’s blood and her fetus’ blood kept separate? Why or why not?

Yes. You know this as well because a mother an child can have different blood types. When you mix incomparable blood types the person involved doesn’t have a good time. Nutrients can transfer between mother and child but not blood itself.
