Microcirculation   function into microcirculation dynamic, microvascular permeability,    microcirculation regulation: Microcirculation dynamic 1. due to the capillary wall cells, smooth muscle cells), peripheral cells, endothelial cells and the effect of fiber, capillaries within the certain pressure can maintain a certain diameter, this phenomenon become blood vessel tone. Blood vessels to keep the certain tension, normally in the pathological blood vessel loss of tension in paralytic relaxation state, blood stream is slow, is seen at this point or blood stagnation of blood plasma separation. 2. arteriole systole and diastole, fine vein wall smooth muscle, which has the ability of active contraction and relaxation. 3. motor vessels cyclical spontaneously, diameter or blood flow changes, the change has nothing to do with heart and breathing, that is called vasomotor. Vasomotor blood vessel function is a measure of tension, the blood vessels are in a state of tension is low
