Answer:
Cutaneous Respiration:
- The skin of frog provides an extensive surface for exchange of gases.
- It is thin richly supplied with blood and kept moist by the mucus and water. The cutaneous respiration is always carried out.
- It is practically the only mode of respiration when the frog is under water.
- Dissolved oxygen in the water is exchanged through the moist surface of the skin by diffusion.
