EVERYDAY SCIENCE

Detailed explanation-1: -How do amphibians breathe? Most amphibians breathe through lungs and their skin. Their skin has to stay wet in order for them to absorb oxygen so they secrete mucous to keep their skin moist (If they get too dry, they cannot breathe and will die).

Detailed explanation-2: -But the ability to breathe through skin, which is called cutaneous respiration, is a common trait in amphibians. The frog is a good example. Essentially, a frog’s skin is thin, and it has a lot of blood vessels. Oxygen diffuses into the skin through those blood vessels. The vessels also allow carbon dioxide to escape.

Detailed explanation-3: -Frogs can also breathe through their skin. They need to keep their skin moist to be able to breathe through their skin, so if their skin dries out they are not able to absorb oxygen. They use their skin to absorb oxygen when underwater, but if there is not enough oxygen in the water, they will drown.

Detailed explanation-4: -Cutaneous respiration, or cutaneousgas exchange, is a form of respirationin which gas exchange occurs across the skin or outer integument of an organism rather than gills or lungs. Cutaneous respiration may be the sole method of gas exchange, or may accompany other forms, such as ventilation.

Detailed explanation-5: -Most amphibians undergo metamorphosis, during which they change from an aquatic animal that breathes through gills to an adult that may have gills or lungs, depending on the species.
