Difference between cutaneous and pulmonary respiration? Answer for class fsc
Answers
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.
Respiration through lungs is called pulmonary respiration. The mechanism of pulmonary respiration: It includes breathing movement, exchange of gases, in lungs, transport of gases by blood and exchange of gase by tissue..
Respiration
Explanation:
Cutaneous respiration is the exchange of gas that occurs via the skin or body surface of animals while pulmonary respiration is the exchange of gas that occurs via the alveoli in the lungs
Cutaneous respiration:
Cutaneous respiration accounts for some gas exchange in certain species of reptiles,exchange of respiratory gases occurs by diffusion and is facilitated by a relatively thin layer of keratin and a rich supply of capillaries in the skin
This type of respiration commonly occurs in insects, amphibians, fishes, turtles
This type of respiration occurs in both air and water
In humans approximately 2 to 3% gas exchange occurs through skin while pulmonary respiration is the main type of respiration which occurs in humans
Pulmonary respiration:
There are two processes which occurs in this type of respiration: inhalation and exhalation
By inhalation air is brought back into the lungs while through exhalation air is released into the atmosphere
