In TCM theory, a channel (meridian) links an internal organ system with a line of points on the surface of the body.

In TCM, the Large Intestine channel is paired with the Lung channel. Traditional teaching links it with the bowel and elimination, the nose and sense of smell, and the teeth and gums.
