Final answer:
In the anatomical position, Yang meridians flow upward according to traditional Chinese medicine practices, representing active and rising energy.
Step-by-step explanation:
When standing in anatomical position, Yang meridians flow upward. This is in line with the principles of traditional Chinese medicine, where Yang represents activity, heat, and light and is often associated with a rising or active energy. In contrast, Yin meridians typically flow downward, representing passivity, cold, and darkness. The concept of meridians is central to acupuncture and other modalities of Chinese medicine, where these pathways are believed to carry qi (life energy) throughout the body. While there is no scientific basis for the existence of meridians, they are an important part of traditional Chinese medical theory.
