The movement of the erythrocytes takes place passively under the influence of the plasma flow and under elastic deformation (armor chain rotation of the membrane); the less flexible nucleus-containing blood cells (lympho- and leukocytes), on the other hand, can cause the local blood flow to be reduced. Slow down blood flow; carried thrombocytes - if not clumping - do not cause any significant flow obstruction. Functional acceleration of microcirculation manifests itself in hyperemia (increased blood volume). Disturbances of microcirculation result from a marked reduction in blood pressure (e.g. in shock), narrowing and displacement of the small arteries and capillaries (e.g. arterial occlusive disease, microembolia, venous backwater (thrombosis), increased blood viscosity.
