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.
The small intestine is one of the "fu" organs stipulated by traditional Chinese medicine (TCM).
It's not mentioned if the small intestine is considered to be an "fu" organ or not, just because the large intestine is doesn't mean the small intestine can't be as well. It's difficult because the text mentions the large intestine so the system assumes it must be incorrect for the small intestine to be considered one as well.
