| 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) |
| abdominal pressure | Pressure surrounding the bladder; estimated from rectal, gastric, or intraperitoneal pressure. (05 Mar 2000) |
| absolute pressure | Pressure measured with respect to zero pressure. Compare: gauge pressure. (05 Mar 2000) |
| acoustic pressure | In ultrasound, the instantaneous value of the total pressure minus the ambient pressure; unit is pascal (Pa). (05 Mar 2000) |
| air pressure | The force per unit area that the air exerts on any surface in contact with it. Primarily used for articles pertaining to air pressure within a closed environment. (12 Dec 1998) |
| atmospheric pressure | The pressure at any point in an atmosphere due solely to the weight of the atmospheric gases above the point concerned. (12 Dec 1998) |
| back pressure | Pressure exerted upstream in the circulation as a result of obstruction to forward flow, as when congestion in the pulmonary circulation results from stenosis of the mitral valve or failure of the left ventricle. (05 Mar 2000) |
| back-pressure renal atrophy | <radiology> Caliectasis without obstruction, due to repeated episodes of obstruction, gradual loss of renal pyramids (12 Dec 1998) |
| barometric pressure | The absolute pressure of the ambient atmosphere, varying with weather, altitude, etc.; expressed in millibars (meteorology) or mm Hg or torr (respiratory physiology); at sea level, one atmosphere (atm, 760 mm Hg or torr) is equivalent to: 14.69595 lb/sq in, 1013.25 millibars, 1013.25 × 106 dynes/cm2, and, in SI units, 101,325 pascals (Pa). Synonym: atmospheric pressure. (05 Mar 2000) |
