Why will the segment of lung tissue cut from the fetal pig sink when placed in water?
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.
