| 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. Then the nostrils open allowing air to enter the enlarged mouth. |
