This lesson describes the properties of gas exchange surfaces and shows how Fick’s law of diffusion is dependent on these properties. The PowerPoint and accompanying worksheets have been designed to cover points 2.1 (i & ii) of the Pearson Edexcel A-level Biology A (Salters Nuffield) specification and there is a. WEB Fick 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 The larger the area and difference in concentration is and the thinner the surface is the quicker rate the diffusion

WEB Summary. Fick's laws of diffusion states that the rate at which a molecule moves through a material is proportional to the concentration gradient (the difference in concentrations) between the two ends of the material; and inversely proportional to the thickness of the membrane. Learn and reinforce your understanding of Fick's laws of diffusion. WEB Conversely, by having a short diffusion pathway due to 1 cell thick alveoli walls, this increases diffusion because using Fick's Law it shows that diffusion distance is inversely proportional to diffusion so if one decreases the other increases. These cards focus on what Fick's Law is, how mammals are adapted for efficient gas exchange, and how ...
