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 Bladder channel is paired with the Kidney channel. Traditional teaching links the Bladder with storing and passing urine. On the back, the channel holds the back-shu points, each traditionally linked with one organ: BL-13 with the Lung, for example, and BL-23 with the Kidney.
