TCM recognizes many of the organs familiar to us, but as usual they are thought of dynamically, the reference being to the organs’ supposed functions as much as to their structures. There are six yang organs (gall bladder, stomach, small intestine, large intestine, urinary bladder and triple warmer). There are five yin organs (heart, lungs, spleen, liver and kidneys); the pericardium is sometimes included as well to bring the number to six. (The triple warmer corresponds roughly to the centre of the body: abdomen and mediastinum.)
