(2001) Bentzer et al. 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). What does FILTRATION COEFFICIENT mean?

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. (2001) Bentzer et al. 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).

In our case, this is the pressure exerted by fluid on the capillary walls of the glomerulus or the walls of the  Sep 30, 2019 Blood plasma containing nutrients moves out of capillaries at the arterial end of capillary beds, in a process called filtration, while tissue fluid  However, traditional techniques for measuring capillary pressure such as porous plate, centrifugation and mercury injection are laborious, time consuming and  The filtration rate is the rate (in metres per hour) at which the pool water moves down through the filter during normal operation. It is not to be confused with the flow  Glomerular Capillary Filtration Coefficient (K f ) - Representative of the hydraulic conductance and surface area of the glomerular capillary K f = GFR ÷ Net Filt.

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. K f represents the filtration coefficient – a product of the capillary wall area where flux can actually occur and the permeability of the wall to water flux; P c and P i are the hydrostatic pressures in the capillary and interstitial space, respectively; σ is the reflection coefficient which describes the capillary’s permeability to The net oncotic pressure (π C - π i) should be multiplied by the reflection coefficient, which is a measure of the permeability of the capillary barrier to the proteins responsible for generating the oncotic pressure.

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.
