What organ governs Qi and respiration?

The lung is the organ that governs Qi and respiration in Traditional Chinese Medicine (TCM). In TCM, the lungs are responsible for the intake of air and the distribution of Qi throughout the body. This is crucial because Qi is considered the vital energy that supports all bodily functions, and proper respiration directly influences the quality and quantity of Qi available for the body’s needs. The lungs also play a vital role in regulating the body’s fluid metabolism and supporting the immune system.

In contrast, the heart primarily governs blood and is associated with emotional well-being and the circulation of blood rather than direct control over Qi and respiration. The kidneys are vital for the storage of essence and play a key role in growth and reproduction, while the spleen is responsible for digestion and transformation of nutrients into Qi and blood. Each organ has a distinct role, but the lung's specific function in breathing and Qi regulation makes it the correct choice in this context.
