The hemodynamics of the microcirculation reflect system properties of the involved components. The blood itself is a complex suspension of water, small and large molecules and different cell types. Under most conditions, its rheologic properties are dominated by the different behaviour of fluid and cellular compartments. When perfused through small-bore tubes or vessels, the suspension exhibits specific emergent properties. The Fahraeus-effect and the Fahreaeus-Lindqvist-effect result from the interaction of cellular particles with each other and with the vessel wall. Additional phenomena occur in vascular networks due to the uneven distribution of blood cells and blood plasma at divergent microvascular bifurcations. In order to understand microvascular hemodynamics in vivo but also in artificial microfluidic geometries it is thus necessary to recognize the pertinent system properties on the level of the blood, the microvessels and the microvascular networks or perfused structures.

微血管血流动力学:系统特性1。

微循环的血流动力学反映了相关组件的系统特性。血液本身是水,大小分子和不同细胞类型的复杂悬浮液。在大多数情况下,其流变特性受流体和细胞隔室不同行为的支配。当通过小口径的管子或容器进行灌注时,悬浮液表现出特定的出射特性。Fahraeus效应和Fahreaeus-Lindqvist效应是细胞颗粒相互之间以及与血管壁相互作用的结果。由于发散的微血管分叉处的血细胞和血浆分布不均,在血管网络中还会发生其他现象。
