微循环一般指从微动脉到毛细血管经微静脉回流到静脉系统的血液循环。微血管非常细小,最细的直径只有5μ,相当于头发丝的1/20。用显微镜观察,在低倍镜下血液流动似小河流水,在高倍镜下又如大河奔流。人体从皮肤到各内脏器官,到处都布满着微血管及毛细血管。我国医学家在这方面获得的研究成果,在世界上已占有重要地位。在 Microcirculation generally refers to the blood flow from the arterioles to the capillaries through the venous return to the venous system. Microvessel is very small, the smallest diameter of only 5μ, equivalent to 1/20 hair wire. Observed with a microscope, the blood flow at low magnification like a stream of water in the river, at a high magnification, another example of a large river rushing. The human body from the skin to the internal organs, everywhere covered with capillaries and capillaries. The research results obtained by Chinese medical scientists in this field have occupied an important position in the world. in
