Through the textual research on the TCM anatomical terms of Jing

Mai

Jingmai

Jingsui

Xuemai

etc.

which describe the tissue with the function of "receiving blood

transporting and transforming blood"

it was discovered that Xuemai （blood channel） in the classic of Miraculous Pivot with its meaning and extension was the most suitable expression to reflect the nature of blood vessels in mordern medicine. Therefore

we put forward to definite the word Xuemai （blood channel） as the collective term of blood vessel system of TCM

and try to standardize the knowledge of TCM on blood channel and its pathological changes

for providing the theoretical basis for TCM for treating the diseases of blood vessels.
