WebFick's law is used to measure the rate of diffusion. It states that the rate of diffusion across an exchange surfaces (e.g. membrane, epithelium) is = (surface area x difference in concentration gradient) / thickness of surface. WebThe rate of diffusion can be calculated using Fick’s Law: __Rate of diffusion is proportional to: (surface area × concentration difference ) / thickness of membrane __ This will mean that the rate of diffusion will double if the …
WebApr 23, 2024 · Fick's law of diffusion (equation 7.2.1) describes all the factors that influence the transfer of gas (or flow, V) across a membrane. We will look at each factor in the equation and see how it relates to the physiology of the lung. Pressure gradient (P 1 −P 2 ): The higher the pressure gradient, the greater the transfer of gas, and the ...
