Terrestrial means on land.
Amphibians breathe with lungs. Reptiles always breathe with lungs. 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. Tadpoles and some aquatic amphibians have gills like fish that they use to breathe.
Amphibians such as frogs use more than one organ of respiration during their life. Most amphibians breathe through lungs and their skin. Adult amphibians are lacking or have a reduced diaphragm so breathing via lungs is forced.
Blood leaves the ventricle and enters the conus arterisous which. But as a baby amphibian grows up it undergoes metamorphosis a dramatic body change. 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.
Most amphibians however are able to exchange gases with the water or air via their skin. Early in life amphibians have gills for breathing. Tadpoles are frog larvae.
Most amphibians breathe through lungs and their skin. In order to breathe they must make convulsive movements with their throat in order to generate air in and out. In addition to their lungs amphibians can actually breathe through their skin.
Like all amphibians toads breathe through their skin as well as with their lungs. Contraction of the atria forces blood into the single ventricle the pumping chamber of the heart at separate times. There are a few amphibians that do not have lungs and only breathe through their skin.
