Pig lungs are divided into seven lobes between two different lungs. In the right lung is larger and divided into apical, cardiac, diaphragmatic and intermediate. The left lung is smaller and does not have an intermediate lobe.
The lungs of a pig are smooth. The left lung has four lobes and the right lung has two lobes.
Without lungs, pigs would not be able to breath air, and will die from asphyxiation.
Just as individual pigs differ in size, so do their lungs. Their lungs are rather small for the size of their bodies, so this can lead to respiratory problems for some pigs.
Stratified: I disagree with stratified, the answer is "simple" arrangement.

If you are studying fetal pigs, their lungs will appear dense and compact. This is because they have never taken a breath.
They are located in the thoracic cavity, just like in humans.
