What is the skin of the frog?

Frogs and toads don’t have fur, feathers, or scales on their skin. Instead, they have a moist and permeable skin layer covered with mucous glands. Their special skin allows them to breathe through their skin in addition to using their lungs.

Why is the frog skin loosely attached to the body?

Ribs are generally absent, so the lungs are filled by buccal pumping and a frog deprived of its lungs can maintain its body functions without them. For the skin to serve as a respiratory organ, it must remain moist. The skin hangs loosely on the body because of the lack of loose connective tissue.

What system lies just beneath the skin of the frog?

A frog’s skin can absorb oxygen, which is captured by capillaries lying just beneath the skin’s surface. These capillaries transport the oxygen throughout the frog’s circulatory system, carried by the blood.

In what way does the frog’s skin afford protection?

The skin of amphibians is moist and thin with no scales. Since it is too thin to provide much protection against dehydration or predators, they must employ other means of defense. For example, amphibian skin contains many mucous glands that keep them moist and make them slippery, which helps them escape from predators.

What makes the skin of a frog moist?

In order to keep moist, frog skin contains glands that secrete a slimy mucous layer to protect the skin from drying out and help draw in oxygen through the skin. In the water, the mucous secretions help frogs retain a healthy balance of salt and water within their internal tissues.

What are the innate defences of frog skin?

Figure 1. The physical, chemical, cellular, and microbiological innate immune barriers of frog skin. Frog skin, which is mucosal in nature, contains physical, chemical, cellular, and microbiological barriers that work together in defence against pathogen assault.

Where are hyaluronan molecules found in frog skin?

This non-cellular layer is composed entirely of glycosaminoglycans and glycoconjugates, wherein hyaluronan and dermatan sulphate have been reported as key constituents in various species ( 29, 30 ). Hyaluronan and other hyaluronan-like molecules in the EK layers are predominantly found on the dorsal side of amphibian skin.
