Tissue Fluid


-water is FORCED out of the capillary into the tissues down a pressure gradient

- the pressure is high in the capillary due to heart contraction (ventricular systole)


-water is forced back into the capillary due to there being a higher hydrostatic pressure in the tissues compared to the capillary

-the water reenters via osmosis

-enters via osmosis as plasma proteins are too large to leave the capillary and so their conc. in the capillary increases

-high conc.=more negative water potential in the capillary compared to the surrounding fluid

-XS tissue enters the lymphatic system due to the increase in pressure at the tissues (lymphatic…
