Skin is the respiratory organ in frogs. A thin water film is formed on the skin of frog and to retain this thin film of water for long time, mucus is produced by the mucus glands present in the skin. The O2 gets dissolved into this thin film of water from where it gets diffused into the blood capillaries. And this is the reason, why the skin of frog is richly supplied with blood capillaries. If the skin of frog dries up, the frog dies. The frogs also have lungs but 80% of respiration takes place through the skin.
So, frogs have two respiratory organs
1) Skin
2) Lungs.
Because as it mostly be seen in water and its skin is wet as this phenomenon can be seen on our skins when we place our fingers in water for a long time..
Moist skin helps in respiration. A thin film of water is formed on the surface of the frog, into which the atmospheric oxygen gets dissolved and ultimately diffuses into the blood vessels underlying the skin. This is the reason, the skin of frog is richly vascular. Some amphibian species don't even have lungs but obtain all their oxygen this way. Frogs do have lung, though, but they still need to breathe through their skin as well.
I am sure they breath by their skins, they need to keep their skin moist and fresh so they reside near water so the exchange of oxygen occurs through their oxygen-permeable skin.
Because they extract oxygen thru their skin. If it does dry up they either perish or some go dormant.Hope this helped,-Drew
Amphibians need moist skin to be able to easily adapt to dry land or the water. This is because an amphibian's respiratory system must be able to adapt to either condition and thin, moist skin makes this easier.
It is all slimy mainly because snakes and frogs and other amphibians also reptiles usually have moist skin.
one word that they are covered with-mucus

A frog can breath through its skin.
Absorb some oxygen when moist.
The slime on the frog's skin is mucus. It is necessary for the frog's skin to be moise because the frog breathes and drinks through the skin. If it were to dry out, it would suffocate. The mucus secreted by the frog's skin helps keep it moist.
The outer part of a frog is comprised of the skin, which protect the frog and helps keep it moist.
Its a cold blood animal.
toxin
Yes.
Constantly, as they need to be moist to do it and if they dry out they die.
The function is for water, oxygen, and carbon dioxide to pass through it, enabling the frog to either breathe or keep it's skin moist and keep the insides in.
glandular skin has many glands Amphibians have a smooth, glandular skin, but they have adaptations for cutaneous respiration, requiring the skin to be kept moist
