The filtration coefficient is the product of these two components: \(Kf = Area \times \text{Hydraulic conductivity} \) A leaky capillary (eg due to histamine) would have a high filtration coefficient. The glomerular capillaries are naturally very leaky as this is necessary for their function; they have a high filtration coefficient capillary filtration coefficient (CFC) the direction of fluid movem. depends on whether NDF is – positive -> filtration – negative -> reabsorption – zero -> no net movem. occurs 2 hydrostatic and 2 oncotic pressures affect transcapillary fluid exchange (Figure 8.7) – capillary hydrostatic pressure – tissue (interstitial) hydrostatic pressure – 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 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, [Filtration rate = Capillary filtration coefficient (Kf) x Net filtration pressure = Kf x (Pc - Pif + πif - πp) = 10 x (25 - 25 + 10 - (-5)) = 150 ml] 1997-04-01 2021-03-19 What does FILTRATION COEFFICIENT mean?

Capillary filtration coefficient

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). In the rest of the body's capillaries, J v {\displaystyle J_{v}} is typically 5 ml/ min (around 8 litres/ day), and the fluid is returned to the circulation via afferent and efferent lymphatics.

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)

The average effective filtration pressure (EFP) values were 12.2 ± 2.2 and 11.5 ± 2.6 mm Hg. Estimated EFP at the terminal end of the glomerular capillaries was

Colloid osmotic pressure in glomerular capillaries (π GC) = 30 mmHg (depends on plasma Jul 18, 2019 The glomerulus is a set of capillaries which invaginate Bowman's and membrane surface area, designated Kf (the filtration coefficient):. Kf, filtration coefficient, is the water permeability or hydraulic conductance of the glomerular capillary wall. The two factors that contribute to Kf are the water Sep 20, 2020 Kf is filtration coefficient.

Renal vasodilation of afferent arterioles and increased renin release occur via macula densa feedback due to reduced NaCl delivery to the macula densa. 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 The net filtration pressure (NFP) represents the interaction of the hydrostatic and osmotic pressures, driving fluid out of the capillary.

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.
