| 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. (18 Nov 1997) |
| fluid mosaic model | A model used to conceptualise cell membranes, in it, the membranesare described as a structually and functionally asymmetric lipidbilayer studded with embedded proteins that aid in cross-membrane transport. (09 Oct 1997) |
| fluid retention | An abnormal accumulation of fluid in cells, tissues or body cavities that results in swelling. (16 Dec 1997) |
| fluid retinopexy | A procedure to repair a detached retina by holding it in place with a fluid that is heavier than vitreous fluid. (05 Mar 2000) |
| fluid shifts | Translocation of body fluids. Shifts from the lower body to the upper part of the body occur under conditions of actual and simulated weightlessness and have the effect of reducing the total body water content and producing a temporary hypovolaemic state. Shifts are also seen following haemodialysis and are caused by electrolyte imbalances. (12 Dec 1998) |
| fluid therapy | Therapy whose basic objective is to restore the volume and composition of the body fluids to normal with respect to water-electrolyte balance. Fluids may be administered intravenously, orally, by intermittent gavage, or by hypodermoclysis. (12 Dec 1998) |
| fluid wave | A sign of free fluid in the abdominal cavity; percussion on one side of the abdomen transmits a wave that is felt on the opposite side. (05 Mar 2000) |
| follicular fluid | <physiology> A fluid consisting of sex steroid hormones, plasma proteins, mucopolysaccharides, and electrolytes that is present in the vesicular ovarian follicle (graafian follicle) surrounding the ovum. (12 Dec 1998) |
| aberrant ventricular conduction | Abnormal intraventricular conduction of a supraventricular beat, especially where surrounding beats are normally conducted. Synonym: ventricular aberration. (05 Mar 2000) |
| aortico-left ventricular tunnel | Congenital connection between the aorta above exit of coronary arteries and the left ventricle. (05 Mar 2000) |
| arrhythmias, ventricular | Abnormal rapid heart rhythms (arrhythmias) that originate in the lower chambers of the heart (the ventricles). Ventricular arrhythmias include ventricular tachycardia and ventricular fibrillation. Both are life threatening arrhythmias most commonly associated with heart attacks or scarring of the heart muscle from previous heart attack. (12 Dec 1998) |
| arrhythmogenic right ventricular dysplasia | A congenital cardiomyopathy in which transmural infiltration of adipose tissue results in weakness and aneurysmal bulging of the infundibulum, apex, and posterior basilar region of the right ventricle and leads to ventricular tachycardia arising in the right ventricle.
