Tissue fluid leaves as there is a high pressure in the capillaries and the capillaries has small holes so the tissue fluid is pushed out. Then the blood inside still has large proteins which give it a low water potential so the fluid can diffuse(osmosis) back into the blood when it's not being absorbed anymore by cells.
