# 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.

GBHP is the blood pressure in glomerular capillaries, which is about 55mm Hg. 2 . Capsular hydrostatic pressure (CHP) is a back-pressure that opposes filtration

Kf is frequently applied to the glomerular capillaries, which filter water into Bowman's capsule to form urine. Typically, in an adult human, the glomerular filtration pressure is 10mmHg and Kf 12.5mL/min/mmHg, giving a glomerular filtration rate (GFR) of 125mL/min. In this review, we discuss the physiological basis of the capillary filtration coefficient (Kf,c), and its measurement in the small intestine. First the various techniques by which Kf,c can be measured are discussed and assessed; the second part of the review considers the volumetric method of determining Kf,c in more detail, in an attempt to identify the causes of variability in published values for intestinal Kf,c. The majority of estimates of intestinal K f,c are about 0.38 to 0.60 (innervated) to 0.60 to 0.75 (denervated) cm 3 ·min −1 ·kPa −1 ·100g −1.

The difference in carbondioxide (at standard temperature and pressure) between arteries and veins Filtration coefficient From Wikipedia, the free encyclopedia In physiology, Filtration coefficient (Kf) is the product of a biological membrane's permeability to water and the surface area of the membrane.

## The capillary filtration coefficient (CFC), defined as the change in transcapillary fluid exchange induced by a fixed change in transcapillary hydrostatic pressure (22, 33), is suggested to equal LpA (30, 33).

### filtration coefficient: a measure of a membrane's permeability to water; specifically, the volume of fluid filtered in unit time through a unit area of membrane per unit pressure difference, taking into account both hydraulic and osmotic pressures.

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. If the capillary barrier is impermeable to protein, then the reflection coefficient is 1. Traditionally, the reflection coefficient of proteins across the capillary wall is assumed to be approximately one.

### 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
