I believe it's still the lungs, but the skin is a huge factor as well.
The Cloaca eliminates waste from the frogs body
Oxygen and carbon dioxide are exchanged across the lining of a frog's mouth. Oxygen is absorbed from the air into the blood vessels, while carbon dioxide is released into the air from the blood vessels.
ANSWER: If you are asking about respiration, the simple answer to your question is that it doesn't refuse carbon dioxide. When a frog inhales, it breathes whatever is in the air around it. Since normally there is almost no carbon dioxide in the air (less than 0.1%) the frog inhales almost no carbon dioxide. The blood circulating through the lungs quickly absorbs the oxygen out of the lungs and into blood stream while discharging the carbon dioxide in the blood stream back into the lungs. When the frog exhales, it releases the carbon dioxide from the blood back into the air where it quickly diffuses into the air surrounding the frog. Then the cycle repeats.
A frog's skin is permeable, this means it lets water in and out. Frog skins also let oxygen pass in and carbon dioxide pass out.
To aid in the diffusion of oxygen into the body and carbon dioxide out of the body
It absorbs oxygen while at the same time releases carbon dioxide across its surface.
the heart is the main circulatory organ of the frog
the organ is the loin.
The skin of a frog is suitable as a minor respiratory organ because it is thin and moist, allowing for oxygen and carbon dioxide exchange to occur directly through the skin. The capillaries near the skin surface help facilitate gas exchange, making it an efficient way for frogs to breathe, particularly when they are underwater or in environments with low oxygen levels.
The name for the frog eggs is spawn.
It takes oxygen and gives of carbon dioxide, just like every other animal.
Yes any animals' stomach is an organ.
