Amphibians Breathe With Lungs

Terrestrial means on land.

Amphibians breathe with lungs. Most amphibians breathe through lungs and their skin. Most amphibians breathe with lungs as larvae and with gills as adults. 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.

The mechanism of taking air into the lungs. The other means of breathing for amphibians is diffusion across the skin. Amphibians breathe by means of a pump action in which air is first drawn into the buccopharyngeal region through the nostrils.

To do this most of these amphibians use a mouth pump that moves air in and out of their body. Ventilation is accomplished by buccal pumping. Do amphibians breathe through lungs.

All reptiles breathe through their lungs. Many young amphibians also have feathery gills to extract oxygen from water but later lose these and develop lungs. While oxygen is plentiful in the air 200000 parts per million it is considerably less accessible in water 15 parts per million in cool flowing water.

Most start life with gills but later develop lungs for breathing. To aid this diffusion amphibian skin must remain moist. 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.

Adult amphibians are lacking or have a reduced diaphragm so breathing via lungs is forced. There are a few amphibians that do not have lungs and only breathe through their skin. The reptiles lung has a much greater surface area for the exchange of gases than the lungs of amphibians.
