PATHOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -Apart from the lungs, adult amphibians like frog also have additional respiratory surfaces such as the skin and the lining of the buccal cavity. While completely submerged in water, all of the adult frog’s respiration takes place through the skin. This is called cutaneous respiration.

Detailed explanation-3: -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. It’s similar to the process that happens inside our lungs.

Detailed explanation-4: -Skin and Gills Other animals, such as earthworms and amphibians, use their skin (integument) as a respiratory organ. A dense network of capillaries lies just below the skin, facilitating gas exchange between the external environment and the circulatory system.
