Why does a foetus's lungs don't work properly?

The foetus in embedded in fluid called amniotic fluid. Some times the foetus takes a breath in that fluid, just before the delivery. The result is disastrous. If the foetus is born with the fluid in the lungs, it is going to die in most of the cases. The foetus is getting all the oxygen and the nutrition from the mother. This is supplied through the placenta. So the lungs of the foetus are at rest in the womb of the mother.

The nutrients are absorbed through the placenta by the foetus. The foetus gets the oxygen and nutrition from the mother.

The surface area of the contact is very large as compared to the size of placenta.
