Summarized functions i) ii) iii) dissolved in plasma water, do not exit through capillaries, not in interstitial fluid, colloid dispersion, osmotic gradient between blood and. Isf, colloid osmotic pressure prevents loss of plasma from capillaries to. Isf helps maintain plasma volume buffer changes in ph.
