+
+ &nbsp; 10 pO<sub>2</sub>(torr)
- &nbsp; persists as the parachordal plate
+
|| Correct! The difference in oxygen tension in the placenta between the umbilical artery 20 pO<sub>2</sub>(torr) and umbilical vein 30 pO<sub>2</sub>(torr) is therefore about 10 pO<sub>2</sub>(torr). This is significantly less that the maternal arterial 100 pO<sub>2</sub>(torr)/venous 55 pO<sub>2</sub>(torr) difference of about 45 pO<sub>2</sub>(torr).
- &nbsp; all of the above are correct
+
- &nbsp; none of the above are correct

  55 pO2(torr)
  45 pO2(torr)
  10 pO2(torr)
  none of the above are correct
