| infranatant fluid | Clear fluid that, after the settling out of an insoluble liquid or solid by the action of normal gravity or of centrifugal force, takes up the lower portion of the contents of a vessel. (05 Mar 2000) |

| interstitial fluid | The fluid in spaces between the tissue cells, constituting about 16% of the weight of the body; closely similar in composition to lymph. Synonym: tissue fluid. (05 Mar 2000) |
| intracellular fluid | The fluid within the tissue cells, constituting about 30 to 40% of the body weight. (05 Mar 2000) |
| intraocular fluid | <physiology> A transparent liquid contained in the anterior and posterior chambers of the eye, produced by the ciliary process it passes to the venous system via the canal of Schlemm. (27 Sep 1997) |
| intravenous fluid | The administration of a balanced electrolyte solution into the venous circulation. (27 Sep 1997) |
| iv fluid | The administration of a balanced electrolyte (salt) solution into the venous circulation. (27 Sep 1997) |
| thixotropic fluid | A liquid that tends to turn into a gel when left standing, but which turns back into a liquid if agitated, as by vibrations or subjection to adequate shear. (05 Mar 2000) |
| tissue fluid | The fluid in spaces between the tissue cells, constituting about 16% of the weight of the body; closely similar in composition to lymph. Synonym: tissue fluid. (05 Mar 2000) |
| embolism, amniotic fluid | Embolism caused by strong uterine contractions near the end of a normal pregnancy that force amniotic fluid into the maternal circulation. (12 Dec 1998) |
| extracellular fluid | The fluid found outside of the cell or cells and between the cells in a tissue. (09 Oct 1997) |
| extracellular fluid volume | The fraction of body wate rnot in cells; about 25% of body weight. It consists of plasma water (4.5% of body weight), water between cells (interstitial water-lymph, 11.5% of body weight), water in dense bone and connective tissue (7.5% of body weight) and water secretions.See transcellular water, about 1.5% of body weight.. (05 Mar 2000) |
| extravascular fluid | All fluid outside the blood vessels, i.e., intracellular, interstitial, and transcellular fluid's; it constitutes about 48 to 58% of the body weight. (05 Mar 2000) |
| Farrant's mounting fluid | An aqueous solution containing gum arabic, arsenic trioxide, glycerol, and water, used in mounting histologic sections directly from water; some modifications involve addition of potassium acetate to bring the pH up to neutrality and substitution of other preservatives like cresol or thymol for arsenic trioxide.

| fluid | Having particles which easily move and change their relative position without a separation of the mass, and which easily yield to pressure; capable of flowing; liquid or gaseous. Origin: L. Fluidus, fr. Fluere to flow: cf. F. Fluide. See Fluent. A fluid substance; a body whose particles move easily among themselves. Fluid is a generic term, including liquids and gases as species. Water, air, and steam are fluids. By analogy, the term is sometimes applied to electricity and magnetism, as in phrases electric fluid, magnetic fluid, though not strictly appropriate. Fluid dram, or Fluid drachm, a measure of capacity equal to one eighth of a fluid ounce. Fluid ounce. In the United States, a measure of capacity, in apothecaries' or wine measure, equal to one sixteenth of a pint or 29.57 cubic centimeters. This, for water, is about 1.04158 ounces avoirdupois, or 455.6 grains. In England, a measure of capacity equal to the twentieth part of an imperial pint. For water, this is the weight of the avoirdupois ounce, or 437.5 grains. Fluids of the body. <physiology> The circulating blood and lymph, the chyle, the gastric, pancreatic, and intestinal juices, the saliva, bile, urine, aqueous humor, and muscle serum are the more important fluids of the body. The tissues themselves contain a large amount of combined water, so much, that an entire human body dried in vacuo with a very moderate degree of heat gives about 66 per cent of water. Burning fluid, Elastic fluid, Electric fluid, Magnetic fluid, etc. See Burning, Elastic, etc. Source: Websters Dictionary (01 Mar 1998) |
| fluid bilayer model | Generally accepted model for membranes in cells. In its original form, the model held that proteins floated in a sea of phospholipids arranged as a bilayer with a central hydrophobic domain. Although it is now recognised that some proteins are restrained by interactions with cytoskeletal elements and that the phospholipid annulus around a protein may contain only specific types of lipid, the model is still considered broadly correct.
