Escobar · Answer 1

Option C, an enormous surface area for gas exchange

Explanation:

The process of gas exchange in any mammal depends on following factors -

a) Thin membrane of respiratory surfaces involved in gas exchange

b) High speed of diffusing gases

c) High Surface area

d) Solubility (lipid solubility) of carbon dioxide and oxygen

The rate of diffusion of gas across a membrane is directly proportional to the surface area of the membrane through which diffusion is taking place. Thus, the higher the surface area, the higher is the gas exchange.

Hence, option C is correct
