WebApr 11, 2024 · The process of filtration and reabsorption in the nephrons occurs through diffusion and active transport. The concentration gradient of the molecules determines their movement across the membrane. Any impairment in the diffusion process in the kidneys can lead to kidney diseases such as chronic kidney disease or acute kidney injury. WebSignificance of Diffusion: 1. The process of diffusion is involved in the transpiration of water vapours. ADVERTISEMENTS: 2. Gaseous exchange during the process of respiration and photosynthesis takes place with the help of diffusion. 3. During passive salt uptake the ions are absorbed by the process of diffusion. 4.
