Tissue Fluid and Lymph 3.0 / 5 based on 1 rating ? BiologyLymphatic systemASAQA Created by: KateCreated on: 18-03-14 19:01 How fluid leaves the capillaries from the arteriol The hydrostatic pressure is higher than the osmotic pressure/solute potential difference. This cancels the osmotic effect. Fluid flows out of the capillaries. 1 of 4 How fluid enters the capillaries at the venous end The hydrostatic pressure is lower than the solute potential difference. Fluid moves into the capillaries. However, not all fluid is reabsorbed. 2 of 4 How tissue fluid re-enters the blood Tissue diffuses by osmosis into the lymph vessel due to the water potential gradient. Once the tissue fluid enters a lymph vessel it is known as 'lymph'. Lymph is returned to the blood via the subclavian vein. 3 of 4 Hydrostatic pressure Hydrostatic pressure is caused by the ventricles contracting. Factors affecting hydrostatic pressure Further distance from heart Fluid decreases Friction caused by blood cells on capillary walls 4 of 4
