Blood rheology and spreading of blood over porous substrates in the case of complete and partial wetting are reviewed. It is shown that the blood is well described by a model of non-Newtonian shear thinning power law liquid. In the case of complete wetting a theory is developed, which predicts a universal behaviour of radius of blood droplet, contact angle and wetted spot on time. The predicted theoretical behaviour is a good agreement with experimental observation. In the case of particle wetting the experimental data show also a universal behaviour in the case of sufficiently big pore sizes but a new phenomenon was found in the case then red blood cells are bigger than the pore sizes: they accumulate on the membrane surface, which allow serration of plasma and red blood cells without damaging red blood cells.

审查了血液流变学和在完全和部分润湿的情况下血液在多孔基质上的扩散情况。通过非牛顿剪切稀化幂律液体模型可以很好地描述血液。在完全润湿的情况下，发展了一种理论，该理论预测了液滴半径，接触角和湿点及时的普遍行为。预测的理论行为与实验观察结果吻合良好。在颗粒润湿的情况下，实验数据还显示出在孔径足够大的情况下的普遍行为，但在红细胞大于孔径的情况下发现了新现象：它们积聚在膜表面，从而允许血浆和红细胞呈锯齿状，而不会损坏红细胞。
