    FORMATION OF TISSUE FLUID AND EXCHANGE OF MATERIALS IN THE CAPILLARY NETWORK In a capillary network, two opposing forces mainly determine the movement of fluid between the blood and tissue fluid: (1) the hydrostatic pressure difference and (2) the osmotic potential difference between the blood and the tissue fluid. In the part of the capillary network near the arterial end, blood pressure is much higher than that of the tissue fluid so that the difference in hydrostatic pressure exceeds the osmo...
