WebOct 11, 2024 · Fick’s first law of diffusion states that the movement of solute takes place from higher concentration to lower concentration. Across the concentration gradient. The formula is fick’s. J = − D d ϕ d x. Where. J is a diffusion flux. D is diffusivity. Φ is concentration. X is position. WebBefore we go through how the alveoli are adapted for this, it may be useful to remember Ficks Law: the rate of diffusion = (surface area x concentration gradient)/distance of diffusion pathway. Faster diffusion = larger surface area, steeper concentration gradient, and shorter diffusion pathway. how to ground a vacuum cleaner https://jessicabonzek.com
