What are the features of respiration in amphibians in relation to life in two environments?
September 13, 2020 | Education
| The respiratory organs in amphibians in terrestrial conditions are the skin and lungs, and in aquatic larvae – the skin and gills. The lungs are thin-walled sacs with a small gas exchange surface that provides only 50% of the body’s oxygen demand. Therefore, additional gas exchange is carried out through the moist surface of the skin, abundantly penetrated by blood capillaries. An amphibian immersed in water completely switches to skin respiration.
