no the lungs and the pumonary circuit do not operate in the fetus until birth
When the lungs do not function the backup respiratory system takes over the function of the lungs. This is true in a fetal pig.
Yes it does, only no air is supplied because it is in amniotic fluid. The lungs and the diaphragm function during fetal development in order to prepare for breathing air after birth. During the time in the uterus, the gas exchange is done by the mother through the umbilical cord and her lungs.
The function of the lungs in a fetal animal is to supply oxygen. This is considered to be one of the most hard working organs in the body.
Fetal lungs are not functioning; no organism can start to breathe while immersed in amniotic fluid. Lungs only begin to function at birth.
It is an alternate way for the blood to flow during fetus development. The alternate blood flow before birth is necessary because the fetal lungs are not yet functioning.
To help pump oxygen to the pigs lungs.....:)

lungs
It really has no function just as in any other fetus. Blood flow to the tissues there are at a normal rate just as to the feet and head. It isn't until the fetus is born that the lungs function as a gas exchange organ.
