十二經(jīng)脈的循行交接規(guī)律是：①相表里的陰經(jīng)與陽經(jīng)在手足末端交接，如手太陰肺經(jīng)在食指端與手陽明大腸經(jīng)相交接；手少陰心經(jīng)在小指端與手太陽小腸經(jīng)相交接；手厥陰心包經(jīng)在無名指端與手少陽三焦經(jīng)相交接；足陽明胃經(jīng)在大趾內端與足太陰脾經(jīng)相交接；足太陽膀胱經(jīng)在小趾端與足少陰腎經(jīng)相交接；足少陽膽經(jīng)在大趾外端與足厥陰肝經(jīng)相交接。②同名的陽經(jīng)與陽經(jīng)在頭面部交接，如手足陽明經(jīng)交接于鼻旁，手足太陽經(jīng)交接于目內眥，手足少陽經(jīng)交接于目外眥。③相互銜接的陰經(jīng)與陰經(jīng)在胸中交接，如足太陰經(jīng)與手少陰經(jīng)交接于心中，足少陰經(jīng)與手厥陰經(jīng)交接于胸中，足厥陰經(jīng)與手太陰經(jīng)交接于肺中。
