Like in the title. Could someone explain to me how does the whole blood-feeding work throughout pregnancy? And also possibly the order in which the changes related to this issue happen in the mother’s body?
I have an extreme vague understanding about the mother’s blood going through the placenta and something happening there that then moves the nutrients to the fetus, but other than that it seems like black magic to me.
How is it that their blood doesn’t mix? (or maybe it does?)
Is the placenta connected to both circulation systems, but somehow distinguishes the two?
There are probably so many other questions I can’t come up with right now..
Any info would be welcome, because it blows my mind and I still can’t comprehend how it works xd
