Fricks law of diffusion physiology
WebFour main factors, also known as Fick’s Law, influence the rate at which gasses will cross the layers of the respiratory membrane. They are: 1) thickness of the membrane; 2) surface area of the membrane; 3) diffusion coefficient of gasses in relation to the membrane; and 4) partial pressure differences of the gasses. WebFick's 1st law of diffusion. Diffusion occurs in response to a concentration gradient expressed as the change in concentration due to a change in position, . The local rule for movement or flux J is given by Fick's 1st law …
