net filtration pressure of the interstitial fluid is higher at the venous end than it is at the arterial end

Detailed explanation-1: -the net filtration pressure of the interstitial fluid is higher at the arterial end than it is at the venous end. the net filtration pressure of the interstitial fluid is higher at the venous end than it is at the arterial end. the osmotic pressure is higher at the arterial end than it is at the venous end.
Detailed explanation-2: -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.
Detailed explanation-3: -Net filtration occurs near the arterial end of the capillary since capillary hydrostatic pressure (CHP) is greater than blood colloidal osmotic pressure (BCOP). There is no net movement of fluid near the midpoint since CHP = BCOP. Net reabsorption occurs near the venous end since BCOP is greater than CHP.
Detailed explanation-4: -Approximately what percent of fluid that exits the capillaries at the arterial end renters the capillaries at the venous end? The lymphatic capillaries reabsorb as much as 20% of the fluid lost by the blood capillaries. The net osmotic pressure is equal at both the arterial and the venous ends of the capillary.
