Answer by Yaybob
from gills to lungs

The tadpole is the aquatic larval form of the amphibian (frog in this case), a descendent of the fish which retains its gill apparatus for extacting dissolved oxygen from the water.

After metamorphosis, the frog switches over to an air-breathing lung system and hops onto the land

From http://en.wikipedia.org/wiki/Amphibian
“The most obvious part of the amphibian metamorphosis is the [1] formation of four legs in order to support the body on land. But there are several other changes: [2] the gills are replaced by other respiratory organs, i.e., lungs, [3] the skin changes and develops glands to avoid dehydration, [4] the eyes develop eyelids and adapt to vision outside the water, [5] an eardrum is developed to lock the middle ear and [6] the tail disappears. .
