Assume that in a particular capillary the pressure at the arteriolar end is 35 mmHg and it decreases linearly with distance to 15 mmHg at the venule end. Assume the capillary is 500 mm long. Assume further that the hydrostatic pressure in the ISF is 2 mm Hg and is constant. The oncotic (osmotic) pressure inside the capillary is 25 mm Hg and is constant. The oncotic pressure of the ISF is 3 mmHg. Is there a filtration or reabsorption of fluid at the arteriolar end? What is the net driving force? Is there a filtration or reabsorption of fluid at the venule end? What is the net driving force? Determine where along the capillary the net driving force for filtration is zero.
