- AFish gills are for hot environments, human lungs for cold.
- BFish gills are for dry air, human lungs for humid air.
- CFish gills are for extracting oxygen from water, human lungs from air.
- DFish gills are for land, human lungs for water.
Gills in fish are specialized structures for absorbing dissolved oxygen directly from water, whereas lungs in humans are adapted to extract oxygen from the air we breathe.
