Question

what helps frogs to breathe underwater

Answer 1

When frogs are tadpoles they breathe underwater through their internal gills and their skin. Later on in life they develop into land animals and develop lungs for breathing air. Frogs breathe with their mouths closed and the throat sack pulls air through the nose and into their lungs. Their throat movements pull air through the nostrils and back into the lungs, then they breathe out with their bodies contracting. Frogs nostrils are placed on top of their head so that they are able to breathe at the same time that they are in the water so that they can always be on guard.
