Why is hydrostatic pressure low in the interstitial fluid?

The force of hydrostatic pressure means that as blood moves along the capillary, fluid moves out through its pores and into the interstitial space. This movement means that the pressure exerted by the blood will become lower, as the blood moves along the capillary, from the arterial to the venous end.Click to see full answer. Thereof, what is interstitial fluid hydrostatic pressure?interstitial fluid hydrostatic pressure (IFHP): force exerted by the fluid in the tissue spaces. net filtration pressure (NFP): force driving fluid out of the capillary and into the tissue spaces; equal to the difference of the capillary hydrostatic pressure and the blood colloidal osmotic pressure. what causes hydrostatic pressure in the capillaries? Hydrostatic pressure is a force generated by the pressure of fluid on the capillary walls either by the blood plasma or interstitial fluid. The net filtration pressure is the balance of the four Starling forces and determines the net flow of fluid across the capillary membrane. Beside this, why is interstitial hydrostatic pressure negative? Due to Positive Hydrostatic Pressure of Blood fluid enters interstitial compartment. And amount of blood absorbed by lymph is slightly more than the blood pushed in interstitium. This creates a negative interstitial pressure.What happens when hydrostatic pressure decreases?In other words, as the hydrostatic pressure gradient (PC – Pi) decreases owing to the rise in interstitial pressure, fluid filtration will be attenuated. However, large increases in tissue interstitial pressure can lead to tissue damage and cellular death.
