WebGiven the following numbers, calculate the net filtration pressure (NFP) in the nephron: hydrostatic pressure in glomerular capillaries (HPGC) = 75 mmHg osmotic pressure in glomerular... WebThe hydrostatic pressure in the glomerular capillary is 4-6 times higher than the hydrostatic pressure in the peritubule capillary so that approximately 25% of the plasma is filtered. The bulk of the filtrate is subsequently reabsorbed by the peritubule capillary network.

WebQUESTION 40 Given the following measurements, calculate the filtration fraction: glomerular capillary hydrostatic pressure = 50 mmHg; Bowman’s space hydrostatic pressure = 10 mmHg; colloid osmotic pressure in the glomerular capillaries = 30 mmHg; glomerular capillary filtration coefficient (Kf) = 8 mL/min/mmHg; renal plasma flow = 500 mL/min. A. … WebPeritubular capillaries are minute blood vessels, which actively reabsorb and secrete substances into the lumen of the nephron. The blood to these capillaries is provided by the efferent arteries. An increase in efferent arteriolar resistance results in the reduction of renal blood flow to the peritubular capillaries.
