Amphibians Breathe With Lungs
Amphibians such as frogs use more than one organ of respiration during their life.
Amphibians breathe with lungs. These are then closed and the air is forced into the lungs by contraction of the throat. By the time the amphibian is an adult it usually has lungs not gills. Many young amphibians also have feathery gills to extract oxygen from water but later lose these and develop lungs.
Adult amphibians are lacking or have a reduced diaphragm so breathing via lungs is forced. In addition to their lungs amphibians can actually breathe through their skin. The mechanism of taking air into the lungs.
Early in life amphibians have gills for breathing. The amphibian tadpole resembles a fish. No matter how big or small the mammal is they always use their lungs to inhale oxygen and exhale carbon dioxide.
Birds face a unique challenge with respect to breathing. Do toads have gills or lungs. In order to breathe they must make convulsive movements with their throat in order to generate air in and out.
A few amphibians dont bother with lungs and instead absorb oxygen through their skin. Amphibians breathe through lungs. Most amphibians breathe with lungs as larvae and with gills as adults.
They breathe through gills while they are tadpoles. As amphibian larvae develop the gills and in frogs the tail fin degenerate paired lungs develop and the metamorphosing larvae begin making excursions to the water surface to take air breaths. As long as their skin is moist they can absorb oxygen directly from the air or water through the skin.
