A fetal pig's lungs are similar to an adult's in the interior. The difference is that it is much smaller.
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.
Both have 3 .
It looks like a clear glue that holds organs in place

The esophagus of a fetal pig, like many organs and body parts, looks very similar to that of a human. It is a long narrow tube, pinkish in color, with cilia lined in the inside (to help push down the food). Click on the link below for pictures of a fetal pig esophagus:

Healthy lung tissue from an adult pig will float in formalin because there is a (relatively) large volume of air trapped in the alveolar sacs. Fetal pigs haven't taken a breath yet, so there is no air in the alveolar sacs. This is why the lung tissue from a fetal pig will sink in formalin. Incidently, this is also how medical examiners can determine if a child was stillborn or was born alive and then died - check to see if a section of lung from autopsy floats in the formalin.
The fetal pig has a four-chambered heart and not three-chambered. The chambers are divided between the upper and the lower chambers.
