Fetal Circulation and Baby's First Breath

Annals of Medical School discusses how the circulation is different before birth so that blood from the mother can oxygenate the growing fetus, and how this changes as a response to the boost of oxygen when the newborn baby first breathes. www.annalsofmedicalschool.blogspot.com

Yeah as commented before Mother's blood does NOT go into the fetus' circulation. Mother's blood goes into the placenta where an exchange occurs of nutrients and oxygen occurs, but the mother's blood goes back to her heart. The baby can have different blood type from the mother so if her blood went into fetus, agglutination can occur from clashing antigens with antibodies

Apologies for any confusion in that comment, it is a simplification clearly, and refers to the directionality of the blood (which is always that of the fetus) and not the actual source of the RBCs. Blood going "to or from" the mother was intended to illustrate the direction of fetal blood flow, so I apologize if that seemed confusing; "to or from" the placenta would be perhaps more clear.

I wonder if it makes a difference in where your first breath comes from? The state of the air in the location of your birth... dirty? clean? lush with plants? cold? wet? dry?

I found it very witty the way you mentioned holding your breath for nine months. Are you a cardiopulmonary doctor?

Thanks for this. I'm in nursing school in NJ and this really helped clear up some questions about fetal circulation.
