Lungs collect oxygen.
Helps with breathing by pushing the lungs when you exhale.
It pumps blood to the lungs and back into the left ventricle
Pig lungs.
Lungs are organs of purifying oxygen in the body, they breath in i.e. inspiration, the fresh air carrying oxygen, and breath out i.e expiration the CO2
The pig has not yet used the lungs to breathe, so therefore they lungs have not been inflated and filled with air.
The main function of a pig's trachea is to breathe. It is part of system of passages that allow air into the lungs.
When the lungs do not function the backup respiratory system takes over the function of the lungs. This is true in a fetal pig.

If the umbilical cord is not cut off it will deteriorate after the pig makes full use of its lungs. The pig uses its lungs immediately after it is born.
