In traditional Chinese medicine (TCM), the so-called 脏腑 refers to all the internal organs in the human body, which are composed of two distinct parts respectively called 脏, usually translated as 脏-organs or 脏-viscera, and 腑, often rendered as 腑-organs or 腑-viscera. The 脏 is also known as 五脏 Jit in Chinese because it includes five major internal organs, namely heart, liver, spleen, lung and kidney. The 腑 is also known as 六腑 in Chinese because it includes six major internal organs, namely large intestine, small intestine, bladder, gallbladder, uterus and Sanjiao (also commonly known as triple energizer).
