Which zang organs are affected by Qi deficiency?

The correct answer identifies the Lung, Spleen, Heart, and Kidney as the zang organs affected by Qi deficiency, which can be understood through the principles of Traditional Chinese Medicine.

Qi is considered the vital energy that sustains life and is essential for the proper functioning of all organs. Each of the mentioned zang organs plays a crucial role in the generation, distribution, and storage of Qi.

The Spleen is particularly fundamental in Qi production, as it transforms food into postnatal Qi and Blood. If the Spleen is deficient, it leads to an inadequate supply of Qi. The Lung, on the other hand, is responsible for the intake of Qi from the air and working with the Spleen to ensure that Qi is available to the body. A deficiency in the Lung can result in reduced energy and vitality.

The Heart, as the monarch of the zang organs, governs Blood and houses the mind (Shen). Insufficient Qi can lead to palpitations, fatigue, and other symptoms indicating that the Heart's function is compromised. The Kidney is also involved in the storage of Essence, which is closely linked to Qi; Kidney Qi deficiency can manifest in a general lack of energy and strength.
