The process by which cells oxidize food materials with the production of energy and release of carbon dioxide

It is referred to as respiration.It is how animals respire, or breathe. We

humans respire with lungs. Not all animals have lungs. For example, fish

have gills, which they use to respire. Frogs breathe through their skin.

What is Cutaneous Respiration?

Cutaneous respiration is breathing through the skin; in some vertebrates the body surface has become highly vascularized for gaseous exchange. Such exchange is of particular importance in the class Amphibia, where mucous glands in the skin maintain a moist respiratory surface.

Frog belongs to class Amphibia under vertebrates.

Cutaneous Respiration In Frog

It is an amphibious animal which can live both on land and in water.Skin is very important organ through which one third of the total oxygen is obtained.

When it is in water it respires through skin.

Frog always keeps its skin moist, because it secretes mucous on to the skin (Mucous layer).

The mucous layer retains water and reduces evaporation of water from body.

To keep the skin wet and moist, frogs jump into water very frequently.

Exchange of gases take place through skin.

Cutaneous Respiration In Frog?

A frog is an amphibian, but adult frogs do not have gills. They absorb oxygen from the water through their skins, using special blood vessels.

If the oxygen level in water is too low, frogs will move around to increase the water flow across the skin. Some frogs have creased skins that can increase their surface area.
