Course of the Channels and Point Qualifications
### Lungs Channel (Hand-Taiyin)
Course: The internal pathway of the Lungs Channel begins in the abdomen and descends to connect with the Large Intestine. From the Large Intestine it ascends upward, crosses the stomach, passes through the diaphragm and enters the Lungs. It continues to ascend along the trachea and larynx. From there the Channel turns laterally, runs across and emerges at LU 01. The surface pathway of the Lungs Channel, starting from LU 01, passes over the shoulder to the anterior aspect of the upper arm, descends along the lateral septum of the biceps femoris muscle to the transverse cubital crease. From here it descends the anterior aspect of the forearm to the traverse carpal crease at the wrist. It traverses the thumb and terminates at the radial corner of the nail of the thumb at LU 11.
