The defensive function of defensive in ( ') includes the effect of immune system of human body against the pathogen invasion. According to the basic research, it is believed that the circulation of defensive in meridian is interpreted as the flow of interstitial fluid in the low hydraulic resistance channel that is overlapped with lymphatic vessels, transporting the antigen information from interstitium to lymph nodes and generating adaptive immune response.
