The [blank_start]Uterine[blank_end] Veins
Pregunta 21
Pregunta
Why does foetal haemoglobin have a higher affinity for oxygen than adult haemoglobin?
Respuesta
-
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
Pregunta 22
Pregunta
Which hormone prevents the degeneration of the corpus luteum?
Respuesta
-
hCG
-
Oestrogen
-
Testosterone
Pregunta 23
Pregunta
Electrolytes such as Calcium and Iron follow the osmotic gradient and thus these nutrients never pass from foetus to mother during pregnancy.
Pregunta 24
Pregunta
Which three of the following statements are true about Human Chorionic Somatomammotropin (hCS)
Respuesta
-
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
Pregunta 25
Pregunta
