The bladder is closely linked to the kidney organ anatomically and functionally. It receives impure liquids and excretes urine. Its ability to store and discharge rely on the strength of the kidney.
This meridian is the longest and most complex meridian. It starts at the inner portion of the eyelid and travels across the front of the head to the back of the head. It then forms two branches that travel down the back to the sacrum along the spine. It then goes along the middle of the butt, and then to the back of the thigh. The two branches then meet behind the knee. The branches then travel between the calf along the Achilles tendon to the outside of the foot and ends at the outside of the baby toe.
