Answer to Question 1

1. Incorrect. The fetal lungs do not function for respiratory gas exchange in utero.
2. Incorrect. The baby does not simply absorb oxygen from a woman's blood system. Blood and gas transport occur through the placenta.
3. Correct. The placenta functions by supplying oxygen and excreting carbon dioxide to the maternal bloodstream.
4. Incorrect. The placenta delivers oxygen-rich blood through the umbilical vein, not artery.

1, 2, 3, 4. Incorrect. These are all factors that are assessed in a biophysical profile.
