Question

cutaneous respiration in frog

Answer 1

Cutaneous respiration, or cutaneous gas exchange, is form of respiration in which gas exchange occurs across the skin or outer integument of an organism rather than gills or lungs. 

Answer 2

Answer:

• 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.
