WebJun 30, 2015 · Fick's principle can be summarised as " the total uptake of (or release of) a substance by the peripheral tissues is equal to the product of the blood flow to the peripheral tissues and the arterial-venous concentration difference (gradient) of the substance". In other words, CO = VO2 / (Ca - Cv). This principle underlies the gold standard of … WebFeb 2, 2011 · According to Fick's Law for a binary system, the diffusive amount-of-substance flux of species 1 relative to a reference frame moving with the molar average velocity of the two species is given by. where x 1 is the amount-of-substance fraction of species 1 and D 12 is the inter-diffusion coefficient of the two species, sometimes …
