Step-by-step explanation:
The meridians that begin at the chest and end on the hand are the Yin arm meridians: LU (Lung), PC (Pericardium), and HT (Heart). These meridians are part of Traditional Chinese Medicine (TCM) and are linked to the flow of Qi or vital energy within the body. In TCM, meridians are classified as either Yin or Yang based on their location and the type of Qi they carry. The Yin meridians are often associated with the interior and lower energy aspects, while Yang meridians are associated with the exterior and higher energy aspects.
