In normal circumstances, ZuZhiYe constantly generated by weight, and constantly absorbing, keep the dynamic balance, health and ZuZhiYe quantity can maintain relative stability. If this occurs, the dynamic balance of damaged tissue absorbed overmuch or weight reducing generation gap, organization of excessive fluid retention, forming tissue oedema. In this experiment, ligation lymphatic make lymphatic backflow disrupted, ZuZhiYe gaps in organization, can cause tissue oedema. In some cases, capillary pressure inside the losing balance, also can cause excessive ZuZhiYe generation. When injected low permeable vessels of saline solution (typical), capillary pressure inside the crystal due to less than the blood vessels, moisture along osmotic pressure difference between organization and formed into ZuZhiYe outside blood-vessel of increasing - edema

In normal circumstances, continue to generate tissue fluid, and constantly being re-absorption, to maintain dynamic balance, the amount of blood and tissue fluid volume to maintain relatively stable. If this kind of dynamic equilibrium destruction happened organizations generate excessive or reduced reabsorption, organizations will have too much space in fluid retention, edema formation. This experiment, the ligation of lymphatic vessel lymphatic reflux so that disruption, the organization gap in the accumulation of tissue fluid can cause edema. In some cases, capillary osmotic pressure inside and outside it out of balance, it will also cause generation of excessive tissue fluid. When vascular injection of hypotonic solution (0.65% saline), the crystal because of osmotic pressure within the capillary blood vessels of less than, the water along the osmotic pressure difference clearance to enter the organization, forming a vascular increase in tissue fluid - edema
