between the cells of the body. They carry the generated chakra and allow the ninja to mold it. If these channels are severed, it is beyond the ability of even skilled medical ninja to repair. On the large scale the chakra circulatory system travels throughout the body and around the internal organs also responsible for creating chakra. This system includes 361 tenketsu, which are tiny pin points through which the chakra flows. The chakra flow can be increased or decreased by manipulating these tenketsu.
