We calculated the driving force for transcapillary fluid transfer.RESULTS: The increase in heart rate and the decrease in systolic blood pressure during lower body negative pressure were similar in diabetic and control subjects. 1994-04-01 2021-02-22 where or andL.are coefficients for thewhole capillary wall andLP, is the filtration coefficient 900 0, C 8004 0-m O 700 0,70 E u 0) 0) Z 700 w 6._000 (0-0 500 0 5 10 15 Timeafter occlusion (sec) Fig. 1.

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. 1979-10-01 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). The capillary filtration coefficient, a sensitive measurement of hydraulic conductivity, was unchanged over 2 h (0.33 +/- 0.03 ml.

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

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. Kf is frequently applied to the glomerular capillaries, which filter water into Bowman's capsule to form urine.
