[The individualization of activities of blood vessels]

The functional activities of blood vessels in various organs have their own characteristics, named individuality of blood vessel. One of the most outstanding characteristics is that the responses of blood vessels in various organs to the same stimulation are different, even contradictory. This physiological characteristic of the blood vessel guarantees that the blood vessel can make adjustable responses in varying parts and under different conditions to fulfil the functional tasks of circulatory system and to meet the demands of blood supply of recipient organs. The study of vascular individualization would benefit to explain the mechanism of blood vessel activities and is also important in the study of pathogenesis of vascular diseases. This paper gives a brief description on the vascular mechanisms contributing to the individualization of blood vessel.
