Question 6
Question
The [blank_start]decidua[blank_end] is the uterine lining (endometrium) during a pregnancy, which forms the maternal part of the placenta
Question 7

Answer
-
umbilical
-
uterine
-
vein
-
artery
Question 15

Question 19
Question
Which vessel(s) carries poorly oxygenated blood from the foetus to the placenta via the umbilical cord?
Umbilical [blank_start]arteries[blank_end]
Question 20
Question
After gas exchange has occurred at the placenta so that the umbilical vein has been perfused with oxygen to go to the foetus, which veins drain the now deoxygenated maternal blood back towards the mother's heart?
The [blank_start]Uterine[blank_end] Veins
Question 21
Question
Why does foetal haemoglobin have a higher affinity for oxygen than adult haemoglobin?
Answer
-
Foetal blood has lower CO2 levels thus leading to a left shift in the oxygen dissociation curve
-
Foetal blood is less acidic thus leading to a left shift in the oxygen dissociation curve
-
Foetal haemoglobin interacts less with 2,3-diphosphoglycerate thus leading to a left shift in the oxygen dissociation curve
-
Foetal blood is a lower temperature than adult blood thus leading to a left shift in the oxygen dissociation curve
Question 22
Question
Which hormone prevents the degeneration of the corpus luteum?
Answer
-
hCG
-
Oestrogen
-
Testosterone
Question 23
Question
Electrolytes such as Calcium and Iron follow the osmotic gradient and thus these nutrients never pass from foetus to mother during pregnancy.
Question 24
Question
Which three of the following statements are true about Human Chorionic Somatomammotropin (hCS)
Answer
-
It is produced as of Week 5 of pregnancy
-
It is produced as of week 8 of pregnancy
-
It decreases insulin sensitivity in the mother, allowing more glucose to be available to the foetus
-
It has a direct effect on the testes of the male foetus, aiding the development of the male sex organs
-
It is directly involved in the development of the breasts during pregnancy
-
It prevents degradation of the corpus luteum by promoting progesterone secretion
Question 25
Question
Which of the following hormones has a very similar structure to TSH and binds to thyroid receptors in some cases leading to Hyperthyroidism in some pregnant women?
Answer
-
hCG
-
Progesterone
-
Oestrogen
-
FSH
-
LH
Question 26
Question
Pregnancy causes an increased demand for Calcium in the body.
This can predispose to which endocrine condition?
[blank_start]Hyperparathyroidism[blank_end]
