Gills,(perch) water moves over the gills and the fishes body takes out the oxygen out of the water.
Frog, takes the oxygen through its skin and processes it Pigeon, delivers oxygen from the air to the tissues and removes carbon dioxide Pig, takes oxygen in through its nose into tis lungs processing and delivering it through out its body via the blood and exhales carbon dioxide |
