Respiratory organs in amphibians?

Amphibians have a variety of respiratory organs that they use to breathe. These include:

1. Skin: Amphibians have thin, moist skin that allows for gas exchange to occur through diffusion. Oxygen is absorbed through the skin, while carbon dioxide is released.

2. Lungs: Most amphibians have simple, sac-like lungs that are used for breathing air. The lungs are relatively small and less efficient than those of mammals, so amphibians also rely on other respiratory organs for gas exchange.

3. Gills: Some amphibians, such as larvae of frogs and salamanders, have gills that are used for breathing underwater. These gills are typically located on the sides of the head and are used to extract oxygen from the water.

4. Buccal cavity: Some amphibians, such as frogs, have a buccal cavity that can be used for gas exchange. This cavity is lined with blood vessels that allow for gas exchange to occur when the amphibian closes its mouth and nostrils.

Overall, amphibians have a combination of respiratory organs that allow them to breathe both in water and on land.
