Premise: The large intestine (Chinese: 大肠/大腸: pinyin: "dà cháng") is one of the "fu" organs stipulated by traditional Chinese medicine (TCM). As distinct from the Western medical concept of large intestine, this concept from TCM is more a way of describing a set of interrelated parts than an anatomical organ. It is a functionally defined entity and not equivalent to the anatomical organ of the same name.
Hypothesis: The concept of "fu" organs is brand new within Chinese medicine.
