Question 6
After about how long is the development of the foetus complete, and how is it positioned in the uterus by then?
The right answer is the one marked above.
280 days, with its head downwards. The muscles of the uterus then contract and push the baby out along the vagina.
The position is not arbitrary: the head is the largest and least compressible part, so once it has passed the rest follows easily. That is why it is settled well before labour begins.
