|
osmotic pressure (OP) in the capillary is high

Detailed explanation-1: -Hydrostatic Pressure CHP is the force that drives fluid out of capillaries and into the tissues. As fluid exits a capillary and moves into tissues, the hydrostatic pressure in the interstitial fluid correspondingly rises. This opposing hydrostatic pressure is called the interstitial fluid hydrostatic pressure (IFHP).
Detailed explanation-2: -Osmotic pressure remains relatively constant over the length of the capillary, but hydrostatic pressure drops sharply as it nears the venule end due to the initial loss of fluid volume. At that point, the interstitial osmotic pressure becomes stronger than the capillary’s hydrostatic pressure.
Detailed explanation-3: -There will be an escape of water and solute into the interstitial space resulting in interstitial edema whenever the hydrostatic pressure is much higher than the osmotic pressure inside the intravascular space.
