Answer 1

Answer:

Thickness of lung membrane

Surface area of lung membrane

Diffusion coefficient.

Answer 2

Lungs...

The lungs are a pair of breathing organs located with the chest which remove carbon dioxide from and bring oxygen to the blood.

The factors that determine how rapidly a gas will pass through the membrane are

(1) the thickness of the membrane

(2) the surface area of the membrane

(3) the diffusion coefficient of the gas in the substance of the membrane

(4) the partial pressure difference of the gas between the two sides of the membrane.
