　"Lungs (HAI)" does not mean the "lungs" meant by Western medicine. "Lungs (HAI)" not only breathes but also carry nutrition and moisture to the whole body and control skin respiration. Moreover, "Qi" required for the body is conjointly generated from "Qi from clear air" taken in by breathing, and "Qi from food and drink" made from "Spleen (HYI)". When "Lungs (HAI)" falls into poor condition, the "large intestine", the "skin", etc. will be affected. Moreover, if " sprinkling function moisture" of "Lungs (HAI)" becomes poor, the skin will dry or dropsy could arise.

　"Kidney (ZIN)" does not mean the "kidney" meant by Western medicine. A "Kidney (ZIN)" controls growth, generation, and reproduction. And it stores the "Essence (SEI)" which is the source of a life. There are "Congenital Essence" and "Acquired Essence" in "Essence (SEI)." "Congenital Essence" is given when we are born by our parents. And "Acquired Essence" is generated from "Qi" and the ""Blood　(KETSU)" which were made from our own body. Both of these "Essence (SEI)" is united and called "Essence of a Kidney (ZINSEI)." "Essence (SEI)" could also be called life energy. If "Essence of a Kidney (ZINSEI)" runs short, senility will appear. When "Kidney (ZIN)" falls into poor condition, "bone", "brain" , "ear", and "reproduction capability" will be affected. The state where the "Kidney (ZIN)" weakened is called "Kidney deficiency (ZINKKYO)", and it could cause of infertility etc.
