What is False statement about colloids is: and explain in detail?
Type of fluid In 1861, Thomas Grahm's investigations on diffusion led him to classify substances as crystalloid or colloids. Intravenous fluids are similarly classified based on their ability to pass through capillary walls that separates the intravascular and intestinal fluid compament. Crystalloid fluids Crystalloid fluids are electrolyte solutions with small molecules that can diffuse freely from intravascular to interstitial fluid compaments. The principle component of crystalloid fluids is sodium and chloride, which can freely pass through capillary well thus the predominant effect of crystalloid fluids is to expand the interstial volume and not plasma volume. Example - normal saline, Ringer's lactate Colloid Fluids Colloid fluid is a saline solution with large solute molecules that do not pass readily from plasma to interstial space.
