? regarding exchange at Placenta

through the placenta:
Oxygen from mother ==> fetus

then:
fetus uses the O2 for ATP production/development

once again through the placenta:
CO2 from fetus ==> mother

is this correct? does anything else go on here that I need to be aware of?

thanks.

sounds good to me.. Just remember blood doesn't mix

Another useful tidbit: remember that at the fetal lungs, blood oxygenation actually DECREASES. It's somewhat counterintuitive... just remember that fetal lungs are not functional early on and the only purpose of blood passing through is to nourish the fetal lung tissue.

fetal hemoglobin binds to O2 more strongly.
