  a. Your baby has all the immune globulins necessary: IgG, IgM, and IgA.
  b. Your baby won't receive any antibodies until he is born and you breastfeed him.
  c. Your baby does not have any antibodies to fight infection.
  d. Your baby has IgG and IgM.

Question 2

  a. The baby's lungs work in utero to exchange oxygen and carbon dioxide.
  b. The baby absorbs oxygen from your blood system.
  c. The placenta provides oxygen to the baby and excretes carbon dioxide into your bloodstream.
  d. The placenta delivers oxygen-rich blood through the umbilical artery to the baby's abdomen.

Answer to Question 1

ANS: D
During the third trimester, the only immune globulins that crosses the placenta, IgG, provides passive acquired immunity to specific bacterial toxins. The fetus produces IgM by the end of the first trimester. IgA is not produced by the baby. By the third trimester, the fetus has IgG and IgM. Breastfeeding supplies the baby with IgA. Your baby does not have any antibodies to fight infection is an inaccurate statement.

Answer to Question 2

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