What is a primary function of Zang organs?

The primary function of Zang organs is to store fundamental substances, which include Essence (Jing), Blood (Xue), Qi, and Spirit (Shen). In Traditional Chinese Medicine (TCM), Zang organs are considered the organ systems responsible for the storage and synthesis of vital substances that support health and contribute to the overall homeostasis of the body.

Each Zang organ has specific roles. For example:

• The Heart stores the Spirit and governs Blood.

• The Liver stores Blood and helps regulate the flow of Qi.

• The Kidneys store Essence and play a key role in reproductive health and aging.

• The Spleen is crucial for the production and circulation of Blood and Qi through the digestion of food.

These functions highlight the Zang organs' role in nurturing and maintaining vital energy and substances that are essential for the body's operation, contrasting with the functions of Fu organs that are more involved in processing and excreting substances. Understanding this foundational concept is crucial for recognizing how these organs interact and maintain balance within the body according to TCM principles.
