The Chinese discovered the circulatory system more than 2000 years before William Harvey did in the West in 1628. The ancient Chinese had a very advanced scientific understanding of the body and how it works, but they defined it in terms and symbols not known to those in the western world. The acupuncture theory of the ancient Chinese takes into account their deep understanding of the lymphatic, circulatory, vascular, and nervous systems. They were able to influence all of these systems through their selection of acupuncture points on the 14 major pathways.
