Understanding diffusion theory and Fick

WebFick’s Law of Diffusion Definition. The Fick's Principle states that the amount of blood taken up by an organ or the whole body per unit of time is equal to the arterial level of the substance (A) minus the venous level of the content (V) times the blood flow (F) i.e., Q= (A-V)F Q = (A− V)F. WebApplication of Fick’s law. Biological application: f u x = − P ( c 2 − c 1) (from Fick’s first law) Where, P: permeability. c 2 -c 1: difference in concentration.
