Microcirculation is one of the basic characteristics of life, and the place where the organism continuously transmits material, energy and information to the surrounding environment. The single-cell organism can conduct such transmission through cell membrane. However, when organisms have evolved to the stage of mammals (as man), the material, energy and information can only be transmitted to the outside environment by lung, stomach and intestine respectively through trachea and esophagus. The position, function and metabolism of other tissue organs have been formalized. The tissues and cells of these established organs cannot make direct communication with outside environment, and the material, energy and information transmission can only be made through tissue fluid, blood and lymphatic fluid.
Microcirculation is just the flow of blow and lymphatic fluid, which directly participate in material, energy and information transmission of tissues and cells.

In comparison with general circulation, microcirculation has the following four remarkable characteristics:
I. In attribute, microcirculation is both the very ending of the circulation system and the important constituent part of the viscera.
II. In form, microcirculation has both the general characteristics of vessels and the special characteristics of viscera.
III. In function, microcirculation is both the circulating passage and the place of material exchange.
IV. Microcirculation is regulated through the nerve and humor systems of the whole body, and regulated locally.
V. Microcirculation has both the general characteristics of the metabolism of the gaps between blood vessels, lymph ducts, and tissues, and some characteristics of the metabolism of the essential cells of the viscera where it exists.

II. Permeability of Blood Capillaries
III. Regulation of Microcirculation
