Do Amphibians Breathe Through Lungs
They are not spongy types just like the higher mammals like us.
Do amphibians breathe through lungs. Early in life, amphibians have gills for breathing. Many young amphibians also have feathery gills to extract oxygen from water, but later lose these and develop lungs. No matter how big or small the mammal is, they always use their lungs to inhale oxygen and exhale carbon dioxide.
When their skin is moist, and particularly when they are in water where it is their only form of gas exchange, they breathe through their skin. Their skin has to stay wet in order for them to absorb oxygen so they secrete mucous to keep their skin moist (if they get too dry, they cannot breathe and will die). Breathing through their skin allows them to stay underground for long periods.
Instead, the insect respiratory system relies on a simple gas exchange that bathes the insect's body in oxygen and expels the carbon dioxide waste. Breathing through the skin is called cutaneous respiration. A frog can breathe in the water.
Unlike the amphibians, the lungs in reptiles are very well developed. Larval amphibians breathe through gills.some salamander retain those gills into adulthood. No because adult amphibians is breathe from lungs and young amphibian breathe through gills by:magno,jhon christopher what role does an amphibians skin play?
When they metamorphose into frogs, they eventually lose their gills and start breathing through the lungs or through the skin. Amphibians such as frogs use more than one organ of respiration during their life. Tadpoles breathe in water and force it past their external gills, in the beginning, so that tiny blood vessels in their gills can absorb the oxygen in water and put it directly into the blood stream.
To breathe using lungs they use their nostrils and mouth to intake oxygenated air by inspiration. Air can either enter the bronchi into the parabronchi, or it can move to posterior air sacs where the air is then stored. Tadpoles breathe water through gills much like fish do, and as a result, the tadpoles' gills work just like those of fish.
