Formation of qi The qi of the human body is formed through the joint work of the kidney, the spleen, the stomach and the lungs, combining the con
3、genital essence and acquired essence.,4. The movement of qi Ascending, descending, exiting and entering are the four basic movements of qi. In TCM, the physiological state in which the four basic movements of qi are coordinated and balanced is called “harmonious functional activities of qi”. When th

The functions of qi (1) Promoting function A Activate the growth and de

B The

C Promote normal circulation of the essence, blood, body fluid without coagulation and stagnation.,(3) Defending function A Guard the surface of the skin against the exogenous pathogenic factors B Combat the invading exop

9、rious kinds of changes taking place in the body through the movement of qi. Namely, the metabolism of essence, qi, blood and body fluid, and the transformation among them.,6. Classification of qi (1) Primordial qi Origin: It comes mainly from the congenital essence stored in the kidney, passing the
10、san jiao and circulating throughout the body. Function: promoting the growth and development, activating and regulating the functional activities of all the zang-fu organs, channels and collaterals, tissues and other organs.,(2) Pectoral qi Origin: It is a combination of the fresh air inhaled by the
11、 lungs and the food essence derived from water and food transformed and transported by spleen and stomach. It is stored in the chest. Function: it flows through the respiratory tract to promote respiratory movement of the lungs. It fills the heart channel to promote the circulation of qi and blood.,
12、(3) Nutritive qi Origin: It mainly comes from the food essence transformed and transported by the spleen and stomach. It flows within the channels. Function: producing blood and nourishing the whole body.,(4) Wei qi /Defensive qi Origin: It mainly comes from the food essence transformed and transpor
13、ted by the spleen and stomach. It flows outside the channels. Function: guarding the surface of the body, warming the body, regulating the opening and closing of the striae.,II Blood,1Concept of blood 2Formation of blood 3Circulation of blood 4.

The lung is in charge of qi of the whole body and is related to the formation of pectoral qi. The pectoral qi has the function of filling the heart channels to pr
17、omote the circulation of qi and blood.,The spleen controls blood, with the function of keeping the blood flowing within the blood vessels. The liver stores blood and regulates the volume of blood. Besides, the liver governs the free flow of qi, which is one of the important factors for normal blood circulation.,
