What is the function of the lungs? You don't know until you see it.

The lung is located in the chest of the human body and is a very important organ. The lungs play a very important role in the human body. As for the functions of the lungs, they are mainly reflected in many aspects. For example, the lungs are also related to human breathing. When the lung qi is coordinated and orderly, breathing can be kept even and unobstructed.

1. Main Qi controls breathing

The lungs control qi, which was first seen in the "Inner Canon of the Yellow Emperor". "Suwen. The Formation of the Five Internal Organs" says: "All kinds of qi belong to the lungs." The lung controls qi, including the qi of breathing and the qi of the whole body.

(1) The lungs control the flow of breath: The lungs control the flow of breath, which means that the lungs are the place for gas exchange. As stated in Suwen Yin Yang Ying Xiang Da Lun, "The weather passes through the lungs." Through the respiratory function of the lungs, fresh air is continuously inhaled and turbid air is expelled, expelling the old and taking in the new, thus achieving gas exchange between the body and the external environment to maintain human life activities.

(2) Controlling the Qi of the whole body: The lungs control the Qi of the whole body, which means that the lungs are responsible for the generation and circulation of the Qi of the whole body. Therefore, it is said in Suwen Liujie Zangxiang Lun that "the lungs are the root of qi."

2. Main water flow

The lungs are responsible for the circulation of water, which means that the lung's function of dispersing and descending qi promotes and regulates the distribution and excretion of water throughout the body. "Suwen·Discussion on the Meridians" calls it "regulating the water channels." The connotation of the lung's function of transporting water has two main aspects: First, through the function of the lung Qi, the spleen Qi is transferred to the lung's water and the lighter and clearer parts of the essence of water and grain, which are dispersed upward and outward to the orifices of the head and face, and to the skin, fur, and muscles of the whole body to moisten them; the water transported to the skin, fur, and muscles is transformed into sweat under the promotion of the Wei Qi, and is excreted from the body in a controlled manner under the regulation of the Wei Qi. Secondly, through the descending function of the lung qi, the spleen qi is transferred to the thicker parts of the water and essence of water and grain in the lung, and transported inward and downward to other internal organs to moisten them, and the turbid liquid (waste water) produced by the metabolism of the internal organs is transported downward to the kidney (or bladder), which becomes the source of urine production.

3. To treat all meridians and treat joints

The lungs are connected to all the meridians, which means that all the blood in the body flows through the lungs through all the meridians. Through the lungs' breathing, the clear and turbid air inside and outside the body are exchanged, and then the blood rich in clear air is transported to the whole body through all the meridians through the lungs' function of ascending and descending qi.
