| nasal lavage fluid | Fluid obtained by irrigation or washout of the nasal cavity and nasal mucosa. The resulting fluid is used in cytologic and immunologic assays of the nasal mucosa such as with the nasal provocation test in the diagnosis of nasal hypersensitivity. (12 Dec 1998) |

| newtonian fluid | A fluid in which flow and rate of shear are always proportional to the applied stress; such fluid precisely obeys Poiseuille's law. Compare: non-newtonian fluid. (05 Mar 2000) |
| non-Newtonian fluid | <chemistry, physics> A fluid in which the viscosity varies depending upon the shear stress. The effect can arise because of alignment of nonspherical molecules as flow is established or because of suspended deformable particles as in blood. It relates to a fluid in which flow and rate of shear are not always proportional to the applied stress and which does not obey Poiseuille's law. See: anomalous viscosity, Fahraeus-Lindqvist effect, Bingham plastic. Compare: newtonian fluid. (21 Jun 2000) |
| sulcular fluid | Fluid containing plasma proteins, which is present in increasing amounts in association with gingival inflammation. Synonym: crevicular fluid, sulcular fluid. (05 Mar 2000) |
| Dakin's fluid | A bactericidal wound irrigant. Synonym: Dakin's fluid. (05 Mar 2000) |
| supernatant 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 upper portion of the contents of a vessel. (05 Mar 2000) |
| dentinal fluid | The lymph or fluid of dentin. It is a transudate of extracellular fluid, mainly cytoplasm of odontoblastic processes, from the dental pulp via the dentinal tubules. It is also called dental lymph. (12 Dec 1998) |
| synovial fluid | <anatomy> Joint fluid, a viscous fluid which lubricates the joint. (27 Sep 1997) |
| 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) |
