Explanation:
Detailed explanation-1: -Dialysis is a separation process in which concentration gradient works as a driving force to separate solute and solvent. Due to the concentration difference, diffusion arises and solute passes across the membrane. Unlike pressure-driven process, this process is slow.
Detailed explanation-2: -When the kidneys fail, dialysis can do their job of removing harmful substances and excess water from the body. This is done with the help of technology that makes use of the physical principles of diffusion, convection and osmotic pressure.
