Amphibians Breathe Through Lungs
Reptile lungs, in turn, are formed by multiple alveoli.
Amphibians breathe through lungs. Amphibians are unable to regulate their body temperature. The lungs in amphibians are primitive compared to those of amniotes, possessing few internal septa and large alveoli, and consequently having a comparatively slow diffusion rate for oxygen entering the blood. Most adult amphibians breathe through lungs and/or through their skin.
Reptiles breathe through the lungs. All reptiles breathe through their lungs. Limbs and lungs are for adaptations of life on land and distinguish them from reptiles.
Most of the animals known as amphibians can live on land or in water. Although most of the amphibians have lungs, they usually breathe through their skin and lining of their mouth, whereas most reptiles do not. They breathe through gills while they are tadpoles.
The latter uses them when it goes to the surface, take the o 2 and remains floating, like other amphibians. With the exception of a few frog species that lay eggs on land, all amphibians begin life as completely aquatic larvae. Frogs can breathe through their skin while they are in water and when they are on land.
When they metamorphose and reach their adult state they start to breathe air out of lungs. This enables them to move from aquatic to terrestrial environments during different seasons. Insects, like people, require oxygen to live and produce carbon dioxide as a waste product.
Amphibians use their lungs to breathe when they are on land. They live in the marshes, in their adult life they breathe through the lungs, they take the o 2 of the surrounding air. All adults are carnivorous but larvae are frequently herbivorous.
