PATHOLOGY

Detailed explanation-1: -Most amphibians breathe through lungs and their skin. 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).

Detailed explanation-2: -Reptiles have scales, and their skin is dry. Amphibians do not, and their skin is often moist with mucus, which keeps them from drying up.

Detailed explanation-3: -Most amphibians breathe through both skin and lungs. The frog is an amphibian.

Detailed explanation-4: -The frog has three respiratory surfaces on its body that it uses to exchange gas with the surroundings: the skin, in the lungs and on the lining of the mouth. While completely submerged all of the frog’s repiration takes place through the skin.
