Amphibians Breathe With Lungs
Reptiles always breathe with lungs.
Amphibians breathe with lungs. They breathe through gills while they are tadpoles. Early in life amphibians have gills for breathing. Amphibians live on land and in the water.
Their skin has to stay wet in order for them to absorb oxygen so they secrete mucous to keep their skin moist If they get too dry they cannot breathe and will die. Frogs toads salamanders newts and caecilians are all types of amphibian. Tadpoles are frog larvae.
A few amphibians dont bother with lungs and instead absorb oxygen through their skin. They can now breathe air on land. Adult amphibians either have lungs or continue to breathe through their skinAmphibians have three ways of breathing.
Most start life with gills but later develop lungs for breathing. When a toad is inactive the skin usually absorbs enough oxygen to meet its needs. Amphibians begin their life living underwater breathing through gills and swimming with tails.
As long as their skin is moist they can absorb oxygen directly from the air or water through the skin. Most amphibians breathe with lungs and through their skin. Amphibians breathe through lungs.
Tadpoles and some aquatic amphibians have gills like fish that they use to breathe. Blood leaves the ventricle and enters the conus arterisous which. Frogs despite having 2 lungs lack a diaphragm and respiratory muscles.
