What is the importance cutaneous respiration in frog?
Answers
taneous respiration, which is breathing through the skin.
Amphibians, you may recall, are vertebrate animals (those having a backbone) that complete a portion of their life cycle in water and another portion on land. There are also some completely aquatic, or water-living, amphibians. Because of their dependence on water, many amphibians have retained the traits of their ancestors, including reduced or even absent lungs. Many rely on breathing through the skin, cutaneous respiration, for some or all of their oxygen intake, and especially for carbon dioxide output.
Cutaneous respiration occurs by way of countercurrent exchange, where blood circulating through the skin flows in the opposite direction of the absorbing oxygen or surrounding water. ... This is similar to crosscurrent exchange, which bird lungs use to pick up oxygen.
