Net Filtration Pressure Equation

by -2 views

Net filtration pressure NFP glomerular blood hydrostatic pressure GBHP capsular hydrostatic pressure CHP blood colloid osmotic pressure BCOP. Since filtration is by definition the movement of fluid out of the capillary when reabsorption is occurring the NFP is a negative number.

Net filtration capillary hydrostatic pressure – interstitial fluid hydrostatic pressure – blood COP – interstitial COP So net filtration 28 – -2 – 25 – 4 30 -.

Net filtration pressure equation. Central to the physiologic maintenance of GFR is the differential basal tone of the afferent and efferent arterioles see diagram. It is named after Ernest Starling. The equation for this.

Ie Glomerular blood hydrostatic pressure- glomerular osmotic pressureCapsular hydrostatic pressure 70mm Hg – 28mm HG 20 mmHg. Study your highlighted notes in your text for your test or what your teacher requires. The Net Filtration Pressure NFP at the glomerulus is the difference between the net hydrostatic pressure and the blood colloid osmotic pressure acting across the glomerular capillaries.

Net Filtration Pressure NFP NFP determines filtration rates through the kidney. It is equal to the difference between the CHP and the BCOP. Net filtration pressure is the difference between the net _____ pressure and the net _____ pressure.

The Starling equation describes the net flow of fluid across a semipermeable membrane. Name at least five symptoms of kidney failure. The Starling equation for GFR is GFR Filtration Constant X Hydrostatic Glomerulus Pressure -Hydrostatic Bowmans Capsule Pressure- Osmotic Glomerulus Pressure Osmotic Bowmans Capsule Pressure.

As predicted by the Starling equation defined earlier net fluid flux J v across a capillary membrane is determined by two separate pressure gradientsThe difference between capillary P c and interstitial P t hydrostatic pressures drives fluid extravasationThis efflux is opposed by the difference between capillary π c and. Glomerular filtration rate GFR is the volume of fluid filtered from the renal kidney glomerular capillaries into the Bowmans capsule per unit time. NFP Glomerular Blood Hydrostatic Pressure GBHP – Colloid Hydrostatic Pressure CHP Blood Colloid Osmotic Pressure BCOP _____ _____ can occur if the homeostatic concentrations of K or Na are disturbed.

Determinants of transendothelial fluid flux. The net filtration pressure NFP represents the interaction of the hydrostatic and osmotic pressures driving fluid out of the capillary. Net filtration pressure NFP glomerular blood hydrostatic pressure GBHP capsular hydrostatic pressure CHP blood colloid osmotic pressure BCOP Q.

NET FILTRATION PRESSURE NFP is the total pressure that promotes filtration. This equation is a variation of Starlings law that shows that hydrostatic and osmotic forces work _______ one another to drive the filtration and reabsorption of materials. To calculate NFP we subtract the forces that oppose filtration from the GBHP.

It is determined as follows. The net filtration pressure is the outward pressure minus the inward pressure. In a capillary the net hydrostatic pressure is 40 mm Hg and the net osmotic pressure is 15 mmHg.

Filtration pressure P – π 40 mmHg – 15 mmHg 25 mmHg What happens to the filtration pressure if l mmole of an impermeant neutral polymer is added per liter of plasma. Net Filtration Pressure NFP equation. NFP Glomerular blood hydrostatic pressure GBHP capsular hydrostatic pressure CHP blood colloid osmotic pressure BCOP 10 mm Hg.

It describes the balance between capillary pressure interstitial pressure and osmotic pressure. Also please note on-screen clarifications within the. The classic Starling equation has in recent years been revised.

The Starling principle of fluid exchange is key to understanding how plasma fluid within the bloodstream. Calculate the filtration pressure FP. The net filtration pressure may be determined by the following equation.

Osmotic pressure is the force exerted by proteins and works against filtration because the proteins draw water in.
