The Heart channel originates in the HT organ. Emerging, it spread throught the heart, going downward through the diaphragm to connect with the SI.
The ascending branch from the heart runs alongside the esophagus and goes across the face to the tissues connecting the eyes with the brain (eye system).
The straight branch from the heart goes upward to the LU. Then it turns downward and merges from the axilla at Jiquan (HT 1). From there it goes along the posterior border of the medial aspect of the upper arm behind the LU and PC down to the cubital fossa. From there it descends along the posterior border of the medial aspect of the forearm to the pisiform region proximal to the palm and enters the palm to end at the tip of the little finger to connect with the SI channel.
