How do baby's breath while they are in the womb?

They absorb oxygen through the shared umbilical cord blood.





***edit*** on the fascinating but sad side, a baby can actually be born alive, not ever take a real breath of air and have enough oxygen in it's blood to maintain a heartbeat for close to an hour, before officially passing away.

How do baby's breath while they are in the womb?
they don't breath air like they do outside the womb, they get the benefits of oxygen from you through the placenta. however they practice the motion of using their lungs but all they inhale is amniotic fluid. Once a baby has gone through the transition of birth they can't go back to breathing water.
Reply:babies get oxygen through blood while in the womb. they do not actually take a breath until after birth. their is an opening in the heart that bypasses a babies lungs and it closes off after birth. this opening bypasses the lungs while the baby is in the womb
Reply:they dont, they receive oxygenated blood thru the umbilical cord from you.
