Answer:

The factors on which the gaseous exchange depends are:

Surface Area Of The Membrane: The larger the surface area of a membrane, the more will be the gaseous exchange. Hence, surface area is directly proportional to the rate of gaseous exchange.

Thickness of the membrane: The more thick the membrane will be, the lesser the amount of gases will be able to diffuse through it. Hence, gaseous exchange and thickness of a membrane are inversely proportional.

The Distance Of Diffusion: The distance across which air and blood have to travel to diffuse also determines the rate of gaseous exchange
