Frogs are very easily dehydrated and need to keep their skin moist permanently. To support this the hydrophyle (waterbinding) mucus is sectreted.
The presence of mucous gland secretes mucous which makes the skin moist for respiration
Mucous glands
They only USE one lung, but they have two.
Yes. Frogs (and toads) have mucous glands all over their skin to help keep their skin lubricated. If frogs do not keep their skin moist they will dry out and die. In some species, such as the poison dart frogs, the secretions from these glands are highly toxic. All frogs and toads have a degree of these poisons, even if it is only in retrace amounts, but in some species the concentration of toxins is much greater, providing an effective defence mechanism. The mucous glands in frogs' and toads' skin is different from the parotid glands which some species of toads have just behind their eyes, which contain irritants and other toxins to deter predators.
The mucous the frog secretes from its skin typically has a foul smell and is usually a poison to help ward off predators.
Frogs have underdeveloped lungs, so they must have a moist skin so that oxygen can diffuse into their bodies. Their lungs do not function well enough to be used on their own.
