1
Q
Fick’s law
A
Fick’s law states that rate of diffusion is directly proportional to surface area x difference in concentration ÷ thickness of gas exchange surface.
2
Q
How are capillaries adapted for diffusion
A
Capillaries are 1 cell thick and very near to cells so the thickness of diffusion surface is thin and the distance of diffusion pathway is very short so substance can diffuse swiftly.
