Capillary Exchange II: Bulk Flow and the Starling Equation of Ultrafiltration Video Lessons

Concept

# Problem: Calculate the net filtration pressure at the arterial and venous end.Capillary hydrostatic pressure at arterial end = 35 mmHgPlasma colloid osmotic pressure = 15 mmHgInterstitial fluid hydrostatic pressure = 1 mmHgInterstitial fluid osmotic pressure = 3 mmHg Is the net filtration pressure greater at the arterial end of the capillary than the venous end or is it equal?

###### FREE Expert Solution

Net Filtration Pressure (NFP): interaction of the hydrostatic and osmotic pressures, driving fluid out of the capillary

: equal to the difference between the CHP (capillary hydrostatic pressure) and the BCOP (blood colloidal osmotic pressure)

###### Problem Details

Calculate the net filtration pressure at the arterial and venous end.

• Capillary hydrostatic pressure at arterial end = 35 mmHg
• Plasma colloid osmotic pressure = 15 mmHg
• Interstitial fluid hydrostatic pressure = 1 mmHg
• Interstitial fluid osmotic pressure = 3 mmHg

Is the net filtration pressure greater at the arterial end of the capillary than the venous end or is it equal?
