Why Is Hydrostatic Pressure Low In The Interstitial Fluid?
Why Is Hydrostatic Pressure Low In The Interstitial Fluid? In both tissues under normal perfusion, outflow capacities (venous blood and lymph) are greater than needed for the inflow volume and capillary permeability. Large outflow capacities drain most of the interstitial water and reduce its hydrostatic pressure to 0. What happens when interstitial hydrostatic pressure increases?
