Which organ is responsible for dominating Qi and controlling respiration?

The organ responsible for dominating Qi and controlling respiration is the Lung. In Traditional Chinese Medicine (TCM), the Lung plays a critical role in the regulation of Qi, which translates to energy or vital life force. The Lungs are seen as the primary organ for the inhalation of Qi from the external environment through breathing.

The process of respiration is vital, as it not only brings in oxygen but also helps in the regulation of the body's overall Qi. The Lungs are thought to "govern Qi" by dispersing and descending the Qi and aiding in its distribution throughout the body. Additionally, the Lungs interact with the skin and the exterior by regulating the Wei Qi, which is protective and helps to defend against external pathogens.

This connection between the Lungs, respiration, and the regulation of Qi demonstrates why the Lung is identified as the organ that dominates Qi and controls the respiratory process. Understanding this role highlights the importance of Lung health in maintaining overall well-being and the balance of Qi in the body.
