Amphibian Respiratory System
The respiratory system of amphibians is characterized by a combination of lungs, skin, and sometimes gills for breathing. Amphibians have simple lungs that are used for gas exchange, but they also rely heavily on their skin to absorb oxygen and release carbon dioxide. Some amphibians, such as tadpoles, have gills for respiration in their aquatic larval stage. Overall, the respiratory system of amphibians allows for efficient gas exchange both in water and on land.
