nestevaihdon
Nestevaihdon is the genitive form of the Finnish term nestevaihto, meaning fluid exchange. It refers to the movement and replacement of liquids between two compartments, systems or environments. The concept covers natural physiological processes as well as engineered procedures and industrial operations. Fluid exchange is driven by gradients in concentration and chemical potential, hydrostatic and osmotic pressure differences, and, in technical contexts, by designed flow paths and control systems.
In biology and physiology, nestevaihto describes how fluids and solutes move across membranes and interfaces. Examples
In medical contexts, the term is often linked to dialysis therapies, particularly peritoneal dialysis. Nestevaihdot refer
In industrial and environmental settings, nestevaihto describes the exchange of liquids between vessels, tanks, or reactors
