exchange of fluid that occurs across the capillary membrane between the blood and the interstitial fluid. This fluid movement is controlled by the capillary blood pressure, the interstitial fluid pressure and the colloid osmotic pressure of the plasma. Low blood pressure results in fluid moving from the interstitial space into the circulation helping to restore blood volume and blood pressure.
An increase in capillary pressure will shift fluid into or out of the capillaries
fluid entering the capillary
The shift of intravascular fluid to the interstitial space is called extravasation or leakage. This can occur due to various factors such as inflammation, increased capillary permeability, or imbalance in hydrostatic pressure.
Osmotic pressure is what draws fluid back into the capillary from the tissues.

The capillary cell wall receives blood from the interstitial fluid.
Diffusion
Fluid shift is the transfer of fluid from blood to interstitial fluid (IF). This transfer changes blood and IF volumes.
Fluid leaves the capillary at the arterial end primarily due to the hydrostatic pressure exerted by the blood, which forces plasma and small solutes out into the surrounding tissues. As blood moves through the capillary, the pressure decreases, and osmotic pressure, driven by proteins in the blood, becomes more significant. This osmotic pressure pulls fluid back into the capillary at the venous end, balancing fluid exchange and maintaining homeostasis in the tissues.
