The fetal pig is in amniotic fluid. There is no air in the womb and the lungs do not inflate until the pig is born.

The lungs of a fetal pig do not contain air because a developing fetus receives oxygen and nutrients from the mother's bloodstream through the placenta, not from breathing air. Therefore, there is no need for the lungs to be inflated with air until birth when the piglet starts breathing independently.
