Functions of the Heart
The Heart governs the Blood and controls the vessels.
Commentary: The Heart is responsible for circulating the Blood throughout the body. It depends on Lung Qi for this function. The Qi of the Lungs needs the Blood of the Heart to be nourished. Qi and Blood must be in a harmonic balance to guarantee regular heart beat. If the Qi of the Heart is strong, the vessels are healthy. The pulse is regular and in harmony.
