Interstitial fluid exudation

Interstitial fluid is produced by filtration of blood through the capillary wall, and the amount of tissue fluid produced depends on the effective filtration pressure. The effective filtration pressure of generated interstitial fluid = (capillary pressure + interstitial fluid osmotic pressure)-(plasma colloidal osmotic pressure + interstitial fluid hydrostatic pressure). Because the blood pressure in the capillaries near the venous arteries is higher than that in the capillaries near the venules, tissue fluid is filtered out from the capillaries, and tissue fluid is reabsorbed from the veins. In addition, a small amount of interstitial fluid enters the capillary lymphatic vessels, forming lymph fluid.
