Organs in Yin-yang

In the light of Yin-Yang theory, we can also categorize a human body’s tissues and organs into several classifications. The key point here is, Traditional Chinese Medicine (TCM ) believe that human body is an organic whole. Which means, an organ depend on other organ’s functions and a disease on an organ will create functional disturbance on another organs.
This interdependence is explained by the yin-yang theory with its classification and categorization of organs. For example, the upper part of the body is yang, the lower part is yin; the exterior is yang while the interior is yin, the back is yang and the chest with abdomen is yin.
The internal organs are divided into 2 category which are zang ( heart, spleen, lung, kidney, liver) and fu( intestine, large intestine, gall bladder, stomach, bladder and triple energizer(sanjiao)). Because the zang organ store essence such as qi and body liquid, it is called yin, but the fu organs which transport and transform categorize as yang.
Moreover, all histological structure of human body is categorize as yin while its function is yang. The histological structure here include: the organs, the meridian, the blood, qi, and body fluid.  To be alive a human body histological structure, while the metabolism of qi,blood and body fluid depends on the functional activities of related organs.
In addition, the various functional activities will eventually consume qi, blood and body fluid, and the creation of qi, blood and body fluid need energy. This is a mark on interdependence relationship in yin-yang theory.  Only, when the balance between yin and yang being maintained, it may ensure the normal state of life.
