What half of pregnancy to fat stores accumulate? correct answers first half
Enhanced fat mobilization occurs in what half of pregnancy? correct answers last half
As blood lipid levels increase so do: correct answers Cholesterol and triglyceride levels
Increased cholesterol is used for: correct answers steroid hormone synthesis, by fetus for nerve
and cell membrane formation.
________________ increases lipid formation and storage correct answers Estrogen
Calcium is needed for: correct answers bone formation, increased maternal absorption and
calcium mobilization
Where does sodium accumulate during pregnancy? correct answers in mother, placenta, and
fetus
______________ of sodium during pregnancy is potentially harmful correct answers restriction
____________________ change increased sodium conservation correct answers physiological
What are the functions of the placenta? correct answers Hormone and enzyme production,
Nutrient and gas exchange, Remove waste from fetus
What is the structure of the placenta? correct answers Double lining of cells separating maternal
and fetal blood, The placenta develops from embryonic tissue and is larger than the fetus for
most of pregnancy
What are the nutrients that can be transported across the placenta? correct answers water,
cholesterol, oxygen, ketones
What cannot be transported across the placenta during active transport? correct answers insulin
What does active transport across the placenta involve? correct answers the use of cell membrane
receptors and energy derived from ATP
What factors affect placenta nutrient transfer? correct answers Size and charge of molecules,
Lipid solubility of particles, Concentration of nutrients in maternal and fetal blood
Why is the fetus not a parasite? correct answers Nutrients are first used for maternal needs, then
for placenta, and last for fetal needed, The fetus is harmed more than the mother by poor
maternal nutrition
