ABSTRACT
After the BL channel (below, in blue, on the left-hand image) ends on the lateral aspect of the little toe, the Kidney channel (below, in purple, on the right-hand image) picks up the trajectory on the bottom of the foot. As it travels north, the KI line encircles the medial malleolus, courses over the medial pelvic limb, and arrives at the pubis just off midline. It remains paramedian as it ascends the abdomen and thorax until it ends at the sternoclavicular junction.
