Answer 2

Adult frogs breathe through their lungs and exchange gases through their skin and the lining of their mouths. At the larval stage of their development, frogs lack functional lungs but are able to take in oxygen through a set of gills.
In short they absorb O2 through~ gills, skin, lungs, and mouth.
