Cutaneous respiration

Definition

Cutaneous respiration is the process by which animals exchange gases through their skin. This method of respiration is particularly common in amphibians and some fish species.

5 Must Know Facts For Your Next Test

1. Cutaneous respiration requires a moist skin surface to facilitate gas exchange.
2. Amphibians such as frogs rely heavily on cutaneous respiration, especially when underwater.
3. This form of respiration is less efficient compared to pulmonary respiration but can be vital for survival in certain environments.
4. Not all vertebrates utilize cutaneous respiration; it is more prevalent in animals with thin, permeable skin.
5. Cutaneous respiration can supplement other forms of breathing, like gills or lungs, allowing for greater flexibility in different habitats.
