noun. A system in which finely divided particles, which are approximately 1 to 1,000 millimicrons in size, are dispersed within a continuous medium in a manner that prevents them from being filtered easily or settled rapidly.

noun. The particulate matter so dispersed.

noun. The gelatinous stored secretion of the thyroid gland, consisting mainly of thyroglobulin.

noun. Gelatinous material resulting from degeneration in diseased tissue.

adjective. Of, relating to, containing, or having the nature of a colloid.

noun. A substance (as albumin, gum, gelatin, etc.) which is of a gelatinous rather than a crystalline nature, and which diffuses itself through animal membranes or vegetable parchment more slowly than crystalloids do; -- opposed to crystalloid.

The dispersion medium may be a gas, a liquid, or a solid, and the dispersed phase may also be any of these, with the exception that one does not speak of a colloidal system of one gas in another. A system of liquid or solid particles colloidally dispersed in a gas is called an aerosol. A system of solid substances or water-insoluble liquids colloidally dispersed in liquid water is called a hydrosol.

noun. A particle less than 1 micron in diameter, following the Wentworth scale
