plasma(redirected from plasmas)
Also found in: Thesaurus, Medical, Encyclopedia.
n. also plasm (plăz′əm)
a. The clear, yellowish fluid portion of blood, lymph, or intramuscular fluid in which cells are suspended. It differs from serum in that it contains fibrin and other soluble clotting elements.
b. Blood plasma, especially when sterilized and depleted of cells for transfusion.
2. Protoplasm or cytoplasm.
3. The fluid portion of milk from which the curd has been separated by coagulation; whey.
4. Physics An electrically neutral, highly ionized phase of matter composed of ions, electrons, and neutral particles. It is distinct from solids, liquids, and gases.
Of or relating to a flat-panel display used in televisions, made up of an array of tiny cells each containing a gaseous mixture of xenon and neon that is changed into a plasma state to illuminate a phosphor coating on the inside of the cell.
[New Latin, from Late Latin, image, figure, from Greek, from plassein, to mold; see pelə- in Indo-European roots.]
plas·mat′ic (plăz-măt′ĭk), plas′mic (-mĭk) adj.
1. (Physiology) the clear yellowish fluid portion of blood or lymph in which the red blood cells, white blood cells, and platelets are suspended
2. (Physiology) short for blood plasma
4. (Nuclear Physics) physics
a. a hot ionized material consisting of nuclei and electrons. It is sometimes regarded as a fourth state of matter and is the material present in the sun, most stars, and fusion reactors
b. the ionized gas in an electric discharge or spark, containing positive ions and electrons and a small number of negative ions together with un-ionized material
5. (Minerals) a green slightly translucent variety of chalcedony, used as a gemstone
6. (Cookery) a less common term for whey
[C18: from Late Latin: something moulded, from Greek, from plassein to mould]
plasmatic, ˈplasmic adj
1. the fluid part of blood or lymph, as distinguished from the cellular components.
3. a green, faintly translucent chalcedony.
4. a highly ionized gas containing an approximately equal number of positive ions and electrons.Also, plasm (ˈplæz əm) (for defs. 1-3).
[1705–15; < Late Latin < Greek plásma something molded or formed, akin to plássein to form, mold. compare plastic]
plas•mat′ic (-ˈmæt ɪk) plas′mic, adj.
1. See blood plasma.
2. Protoplasm or cytoplasm.
3. A state of matter similar to a gas but consisting of positively charged ions with most or all of their detached electrons moving freely about. Because the concentrations of free electrons and positively charged ions are nearly equal, a plasma is electrically neutral. Plasmas are produced by very high temperatures, as in the sun and other stars, and also by the ionization resulting from exposure to an electric current, as in a fluorescent light bulb or a neon sign.
1. A gas with roughly equal numbers of negative and positive ions.
2. The fluid part of blood.
