Introduction In order to fully understand the movement of particles across a membrane, one must be knowledgeable of basic concepts concerning diffusion and osmosis. Diffusion can be defined as solutes moving an area having a high concentration to an area having a lower concentration. Diffusion is the outcome of the constant, random motion is the outcome of the constant, random motion of solutes. The Random Thermal Motion (RTM) theory states that particles are constantly taking …showed first 75 words of 740 total…

Metabolic wastes are diffused form the blood in dialysis fluid located outside the dialysis tubes of the artificial kidney. The final result of the concentration of the blood re-entering the body is the same as if it had gone through the body. Osmosis a diffusion play a key role in upholding the body’s homeostasis.
