Question

conlusion of cutaneous respiration

Answer 1

Cutaneous respiration, or cutaneous gas exchange, is a form of respiration in which gas exchange occurs across the skin or outer integument of an organism rather than gills or lungs. Cutaneous respiration may be the sole method of gas exchange, or may accompany other forms, such as ventilation. Cutaneous respiration occurs in a wide variety of organisms, including insects, amphibians, fish, sea snakes, turtles, and to a lesser extent in mammals, excluding humans.

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.
