They need air to operate properly, the fetus develops in fluid until born. The lungs first work shortly after the baby is born.
The fetus does not use its lungs to bring oxygen to the blood. (apex)
Pulmonary circulation is reduced in the human fetus because the lungs are not yet functional for oxygen exchange. Instead, much of the oxygen comes from the placenta via the umbilical vein and bypasses the lungs through the ductus arteriosus and foramen ovale. This allows the fetal lungs to remain collapsed and prevents excessive blood flow through the non-functioning pulmonary circulation.
