Channels
### Functions of the Channels
The channels and network vessels (jing luo) form a network system in the organism in which Qi and Blood circulate. The channels are the main pathways of Qi and Blood, whereas the network vessels are smaller branches ensuring the supply of Qi and Blood to all areas of the body. This system connects the Zang and Fu organs, it connects the body surface with the body interior, and it connects with the extremities and the sensory organs, limbs and joints. This system consists of the twelve regular channels, eight extraordinary channels, twelve divergent channels, and twelve cutanous regions. Normal functioning of the organs is thus ensured and a relative equilibrium is maintained.
