In this how does a frog breathe on land and in water? post we have briefly explained about how do amphibians breathe on land and in water.

How Do Amphibians Breathe On Land and In Water

The frog has three breathing surfaces on its body, which are used to exchange gases with its surrounding environment: the skin, lungs, and the tongue’s lining.

Skin

If the frog is completely submerged, all the frog’s breathing is carried out via the skin. The skin comprises membranous skin that is very permeable to water and has numerous blood vessels. 

The skin is composed of thin membranous tissue that is quite permeable to water and contains a large network of blood vessels. The thin membranous skin allows the respiratory gases to readily diffuse directly down their gradients between the blood vessels and the surroundings. When the frog is out of the water, the mucus glands inside the skin help keep the frog humid, which assists in absorbing oxygen dissolved from the air.

Lungs

A frog can breathe like humans and breathe air through their nostrils before releasing it into their lung. The way they take breath into their lungs is slightly different from that of humans. Frogs don’t have diaphragms or ribs that humans have, which to expand the chest, and thus reducing the pressure inside the lungs and allowing air outside to flow into.

To draw air into the mouth of the frog, the frog lowers the level of its mouth. This causes the throat to expand. The nostrils are then opened, which allows air to enter expanding mouth. The nostrils close, and the air that is in your mouth will be forced in lungs through contraction of surface of the mouth. To eliminate carbon dioxide that is in the lungs, that mouth’s floor is moved down, bringing the air out of the lungs to the mouth. The nostrils then open and the floor of the mouth is raised, pushing the air out of the nostrils.

They also possess a breathing surface in the lining of their mouths where gas exchange takes place quickly. At rest, this is the primary method of breathing. It which only occurs occasionally. This is due to the fact that the lungs that only adults possess are not well developed.
