This is called the whole body capillary filtration coefficient. The filtration coefficient can also be expressed for separate parts of the body in terms of rate of filtration per minute per millimeter of mercury per 100 grams of tissue. On this basis, the filtration coefficient of the average tissue is about 0.01 ml/min/mm Hg/100 g of tissue.

One of these forces is called hydrostatic pressure. In our case, this is the pressure exerted by fluid on the capillary walls of the glomerulus or the walls of the

water permeability or hydraulic conductance of glomerular capillary wall. PGC is hydrostatic pressure in glomerular 13.7.1 Filtration and re-absorption of water within single capillaries. In practice the capillary filtration coefficient for a particular preparation may be calculated if In physiology, Filtration coefficient (Kf) is the product of a biological membrane's Kf is frequently applied to the glomerular capillaries, which filter water into May 17, 2016 state circulation at about 5–10 ml min−1, and capillary filtration rate can (ii) Staverman's reflection coefficient sigma, which modifies the.

Capillary filtration coefficient

1977-07-01 · We found the capillary filtration coefficient value to be 8.3 × 10 −5 cm 3 sec −1 cm H 2 O −1, which, when normalized for the estimated exchange area, is at least a factor of 2 larger than the value found for adult The capillary filtration coefficient (CFC) is assumed to reflect both microvascular hydraulic conductivity and the number of perfused capillaries at a given moment (precapillary sphincter activity). Estimation of hydraulic conductivity in vivo with the CFC method has therefore been performed under conditions of unchanged vascular tone and metabolic The capillary filtration coefficient was measured in human extremities by a simplified technique using the capacitance plethysmograph. The method was validated in terms of consistency of values obtained on the same individual at various times, the correspondence between values obtained on a group of normal persons, and the agreement between values reported here and those of earlier workers the coefficient of capillary filtration can be expressed in ml'min,/mmHg/100ml. Subjects Studied Measurements of the coefficient of capillary filtration were obtained from 19 healthy control subjects, 15 patients with definite or classical rheumatoid arthritis (Ropes, Bennett, Cobb, Jacox, and Jesser, 1959) and no history of oedema, The slope of this line—the capillary filtration coefficient—agreed with previously reported values.

American Journal of Physiology - Heart and Circulatory Physiology. The capillary filtration coefficient (CFC) is assumed to reflect both microvascular hydraulic conductivity and the number of perfused capillaries at a given moment (precapillary sphincter activity).

capillary filtration coefficient (surface area to permeability) What does Pc mean? Pif? Capillary hydrostatic pressure Interstitial hydrostatic pressure. What does σ mean? reflection coefficient If 1 = membrane not permeable to proteins If close to 0 = membrane permeable to proteins.

1) About the glomerular filtration barrier and its relationship to the filtration coefficient.2) How the filtrati In this lesson, you'll learn the following.

the filtrate is a true ultrafiltrate as the glomerular capillaries are essentially impermeable to protein (so oncotic pressure in the filtrate is zero) The hydrostatic pressure in the capillaries is high and does not decrease much along the length of the capillary The net filtration pressure (NFP) represents the interaction of the hydrostatic and osmotic pressures, driving fluid out of the capillary. It is equal to the difference between the CHP and the BCOP. Since filtration is, by definition, the movement of fluid out of the capillary, when reabsorption is occurring, the NFP is a negative number.

The reflection coefficient is high: about 1.0 (i.e. the filtrate is a true ultrafiltrate as the glomerular capillaries are essentially impermeable to protein (so oncotic pressure in the filtrate is zero) The hydrostatic pressure in the capillaries is high and does not decrease much along the length of the capillary

Measuring the capillary filtration coefficient (CFC) from the transvascular fluid filtration following a fixed increase in transcapillary hydrostatic pressure is a common method to estimate capillary hydraulic permeability (conductivity) in an organ. Capillary filtration coefficient is independent of number of perfused capillaries in cat skeletal muscle. / Bentzer, Peter; Kongstad, Lis; Grände, Per-Olof. In: American Journal of Physiology: Heart and Circulatory Physiology, Vol. 280, No. 6, 2001, p. H2697-H2706. Research output: Contribution to journal › Article Capillary filtration coefficient (CFC), vascular resistance (R), and perfusate O2 content were measured in each period. The arterial O2 content fell from fully equilibrated to 0.25 vol% during the use of N2. R fell from about 6 mmHg X min X 100 g X ml-1 during O2 bubbling to approximately 1.0 with N2. Glomerular capillary is more familiarly known as the glomerular filtration rate (GFR).

However, traditional techniques for measuring capillary pressure such as porous plate, centrifugation and mercury injection are laborious, time consuming and

CFC is defined as Capillary Filtration Coefficient somewhat frequently. CFC stands for Capillary Filtration Coefficient. Printer friendly. Menu Search "AcronymAttic.com. Abbreviation to define.
