气、血、津液是构成人体和维持人体生命活动的基本物质。是脏腑、经络等组织器官功能活动的产物，又是脏腑功能活动的物质基础。 In TCM books, qi is always mentioned in the same breath with blood and body fluid, for they are all the fundamental substances constituting the human body and maintaining its life activities. However, among them qi is particularly important for the human body. That is why TCM often explains the life activities of the human body in the viewpoint of qi. For this reason, Zhang Jingyue said: “Man‘s life relies entirely upon this qi.” Classic on Medical Problems(难经) states:“qi is the root of the human body; once the root is damaged, the stem and leaves would turn withered” 气者，人之根本也；根绝则茎叶枯矣. And, also, Basic Questions（素问） points out : “One’s life is the combination of qi of heaven and earth”（天地合气，命之曰人）

Qi is the root of the world 气是构成世界的本原 Qi is the root of the world 《庄子·知北游》：“人之生也，气之聚也，聚则为生，散则为死……通天下一气耳。” 《论衡》：“万物之生，皆禀元气。” 《素问·保命全形论》：“天地合气，命之曰人。”王冰注：“气者，生之母也。” 精与气的关系 精为脏腑功能活动的物质基础(substance)，气是推动和调控脏腑生理活动的动力（power & impetus） “人始生，先成精” “精化为气”

气的概念 Concept of Qi 气是一种具有很强活力的、在人体内不断运动着的、构成人体和维持人体生命活动的最基本物质。 气是人体生命的原动力，它代表脏腑组织的生理功能，如心气、经气。 The classic chinese philosophy believes that the primary state of the universe is qi,the constant movement of which produces all the things in the univese,including life.thus people in ancient china thoutht that the accumulation of qi would produce life while the dispersion of qi would put an end to life. Qi is very active and in constant motion.qi is also extremely fine and invisible.

The production of Qi Qi exists right after the formation of individual life. This kind of qi is inherited from kidney-qi of the parents during pregnancy. So it is called “congenital qi”which is the foundation of the development of new life After birth ,the human body keeps absorbing nutrients from the external world to nourish the congenital qi. This is the acquired source of qi,also known as “acquired qi”. Acquired qi originates from food nutrients and fresh air inhaled into the body. In fact, the congenital qi and acquired qi are just two material sources of qi. The process of qi production also involves the other viscera. The inter-transformation among essence,qi,blood and body fluid influences the production of qi.

Basic patterns of Qi's movement Qi flows throughout the whole body because of its strength and vigor. The movement of Qi is called Mechanism of Qi, which can be generalized as four aspects: ascending, descending, entering and exiting movements, which are based on directions. Ascending refers to the upward movement of Qi from a lower area; descending means the downward flow of Qi from an upper area. Exiting means the outward movement of Qi, and entry indicates the inward movement of Qi. Although the activities of the human body are multiple, they can all be summarized as these four aspects. For example, the dispersing effect of the Lung is a manifestation of the exit and ascent of Qi, while its descending effect is a manifestation of the descending and entering movements of Qi. The ascent, descent, exit and entry movements of Qi are of prime importance in human life. The Kidney Essence, the food Essence transported and transformed by the Spleen and Stomach and the fresh air inhaled by the Lung, will not be distributed over the body to perform their physiological functions if they do not make ascent, descent, entry and exit movements.

气运动的意义 “出入废则神机化灭，升降息则气立孤危。故非出入，则无以生长壮老已，非升降则无以生长化收藏。是以升降出入，无器不有！

气 化 含义：是气的运动而产生的各种变化，是指由人体之气的运动而引起的精气血津液等物质与能量的新陈代谢过程，是生命最基本的特征之一。 形式：精的生成、精化为气、精化为髓、精血同源互化、津液与血同源互化血的化生与其化气生神、津液的化生与其化汗化尿、气的生成与代谢等 体内精气血津液各自的代谢及相互转化是气化的基本形式！

Qi-transformation Qi-transformation means changes caused by the movement of qi, which is the essential cause of the conception,development,growth and decline of life. Life activities concerned with qi-transformation can be divided into three categories. Firstly,through food and respiration the body absorbs nutrients from the external world and transforms them into essence,qi,blood and body fluid essential to the body. Secondly,inter-promotion among the refined substances is the process of automatic regulation,improvement and balance of life. Thirdly,waste substance and turbid qi are excreted out of the body in the process of life. If qi-transformation is weakened,the whole process of life will be in disorder or decline,leading to various diseases. The declination of qi-transformation even leads to death.

Functions of Qi 1. Promoting function of qi Just as wind (highly active air) provides energy to push the sails of a boat or turn the turbine of a windmill, qi provides the active, vital energy necessary for the growth and development of the human body and to perform the physiological functions of the organs, meridians and tissues. In addition, qi promotes the formation and circulation of blood and supports the metabolism of body fluid. If there is a deficiency of qi, its promoting functions are weakened. As a result, growth and development can be affected or delayed, the organs and meridians cannot function properly and blood formation is hampered, leading to a series of health problems

Functions of Qi 2. Warming function In a gaseous state, air contains more kinetic heat energy than in its liquid state. Like air, qi also contains heat energy for the body. Being a heat source, qi warms the body and keeps it at a constant temperature so normal physiological functions can take place. Deficiency of qi can lead to a lowered body temperature, intolerance of cold and cold hands and feet. 3. Defending function In TCM, one of the main causes of disease is the invasion of "Evils"."Evils" are environmental factors that lead to illness. They are classified as wind, summer heat, dampness, dryness, cold and fire. By resisting the entry of ' illness evils" into the body, qi defends against their attack and maintains healthy physiological functions. In western terms, this qi defending function acts like the immune system.

Functions of Qi 4. Consolidation and retention function Qi consolidates and retains the body's substances and organs by holding everything in its proper place. First, qi keeps the blood flowing within the vessels and prevents it leaking out into the tissues. Secondly, qi controls and adjusts the secretion and excretion of sweat, urine and saliva, and keeps body fluids from escaping the body. Thirdly, qi consolidates and stores sperm to prevent premature ejaculation. Lastly, qi consolidates the organs and stops them from descending into a position where they cannot function properly. If qi is deficient, the consolidating function is weakened, leading to various kinds of health problems such as haemorrhage; frequent urination, premature ejaculation and stomach or kidney prolapses (where the organ sinks). The promoting and consolidating functions work in a complementary manner. For example, qi promotes blood circulation and the distribution of body fluids, but it also controls and adjusts the secretion of fluid substances. The balance between these two functions is essential for maintaining a healthy blood circulation and water metabolism.

Functions of Qi 5. Transforming functions Qi also possesses vaporization or transformation functions, which are important for the metabolism of fundamental substances. As suggested by these words, qi may "vaporize" substances in the body and transform them into essence or vital energy. For example, certain actions of qi allow food to be changed into food essence, which is in turn transformed into different types of qi and blood. Indigestible food and waste are also transformed by qi into urine and stools for excretion.

人体之气的分类 元气、宗气、营气、卫气

人体之气的分类

营气与卫气的区别 营 气 卫 气 概念 营气是行于脉中而具有营养作用的气。 营气属阴，又称营阴。 卫气是行于脉外而具有保卫作用的气。 营 气 卫 气 概念 营气是行于脉中而具有营养作用的气。 营气属阴，又称营阴。 卫气是行于脉外而具有保卫作用的气。 卫气属阳，又称卫阳。 生成 分布 营者，水谷精气精纯柔和部分 行于脉中 卫者，水谷之慓疾滑利部分。 行于脉外 功能 化生血液 营养全身 温养脏腑 护卫体表

营气与卫气的联系 营卫二气都源于水谷之精的化生，来源相同。营气与卫气之间又可相互化生，相互资助。营气在脉中，若游出脉外则为卫气；卫气行脉外，若进入脉中则为营气。营气与卫气分之为二，合二为一。 营卫和调，才能维持正常的体温和汗液分泌，人体才能有旺盛的抗邪力量和脏腑的正常生理活动。若营卫二者失和，则可能出现恶寒发热、无汗或汗多，昼不精夜不瞑，以及抗病能力低下而易于感冒等（参见伤寒的麻黄汤、桂枝汤、桂枝加龙骨牡蛎汤等方证）。 营气与卫气的运行 营气与卫气的运行应是：相偕而行，昼行于阳，夜行于阴。昼则卫气起主导作用，夜则营气起主导作用

Types of Qi 1. Inborn qi （primordial qi，元气） Inborn qi is the most original, essential and vital type found in the human body. It possesses prenatal and congenital properties. After conception, "congenital essence" (an essential vital substance inherited from parents) is stored in the kidney, the place from which inborn qi originates. Inborn qi is further nourished by "acquired essence" (food essence derived from digestion) of the spleen and stomach. After this process is complete, inborn qi is ready to travel to the entire body to exert its effects. Starting from the portion between the two kidneys, known as the "vital gate", the qi moves through the triple burner and circulates through the organs, muscles, skin and meridians providing the power source for all of life's activities.

2. Pectoral qi （宗气） Pectoral qi is stored in the chest. It is formed by combining fresh air inhaled by the lungs and food essence derived from the spleen and the stomach. Because pectoral qi concentrates in the chest, it can penetrate the blood vessels of the heart and lungs and move outward during expiration and inward during inspiration. By flowing through the respiratory tract, pectoral qi supports the breathing function of the lungs and affects how loud the voice can be. Its ability to flow through the blood vessels and the heart is important in regulating the heartbeat and supporting the circulation of other types of qi and blood. Pectoral qi also plays a role in keeping the body warm and influences the activities of the limbs

3. Nutritive qi （营气） Nutritive qi, as its name suggests, supplies nourishment to the body. It mainly circulates through the blood vessels with the blood. Sometimes this combination of nutritive qi and blood is referred to collectively as "nutritive blood". Nutritive qi mainly comes from food essence derived by the spleen and stomach's transformation and transportation properties. Starting from the middle burner, nutritive qi goes to the lungs where it enters the main circulation. Nutritive qi has yin properties so it can form into materials needed by other parts of the body. For example, its close relationship with blood allows it to provide some of the necessary substances needed to produce new blood. Nutritive qi also provides the needed nutrients to support the physiological functions of the organs.

4. Protective qi (defensive qi，卫气) Protective qi protects against evils. As previously mentioned, evils are environmental factors that lead to illness. In western terms, protective qi functions like the immune system, which helps prevent disease from occurring or spreading. Unlike nutritive qi, protective qi has yang properties, because it has more functional characteristics. Protective qi also comes from the food essence derived by the spleen and stomach. It moves outside the blood vessels and circulates in different areas from nutritive qi. Internally, it will be distributed to the diaphragm and scattered around the chest and abdominal cavities. Externally, it moves between the skin and muscles providing protection. Protective qi not only guards against illness and disease but also regulates the sweat glands and pores and provides nourishment for the skin, hair and muscles. Although nutritive and protective qi share the same origin, their flow directions, as previously described, are opposite to one another. By balancing their nutritive (yin) and protective (yang) functions, healthy sweating, temperature control and defence functions are maintained.

中医学中精与气概念的区别 精是构成人体的最基本物质，也是维持人体生命活动的基本物质。《灵枢·经脉》说：“人始生，先成精。”“夫精者，身之本也” 气是由精化生的极细微物质，《素问·阴阳应象大论》说：“精化为气。” 精为脏腑功能活动的物质基础，气是推动和调控脏腑生理活动的动力。 精属阴，藏于脏腑而有形；气属阳，运行全身而无形。

The basic concept of blood Blood, mainly composed of the nutrient qi and body fluid,circulates inside the vessels. It is red in color and sticky in texture. Blood functions to nourish and moisten the body. It is vital to the maintenance of life.

The circulation of blood The vessels in the whole body form a relatively close circulatory for blood circulation. Such a system is known as blood vessels in TCM included in the concept of meridians and vessels. The minute capillaries are called blood collaterals

Blood regulation function of viscera Blood is propelled by the heart to circulate in the vessels. Apart from the heart, other internal organs are also involved in the circulation of blood,including the lung,the spleed and the liver. Structurally the lung is connected with all the vessels in the body,known as “the lung facing all the vessels”. The spleed commands blood,making the vessels compact,directing blood to circulate normallu in the vessels and preventing it from flowing out of the vessels. The liver stores blood and regulates the volume of blood. Besides, the liver also governs dredging and dispersing,thus smoothing the activity of qi to promote blood circulation.

血的功能

The physiological functions of blood The physiological functions of blood are to nourish and moisten the body as described in Nanjing. Since blood contains the nutrient qi.it can nourish all the organs in the body. It should be noted that blood is also the important material base for mental activities. If blood is sufficent,there will be dispiritedness;if blood is deficient,there will be dispiritedness;if blood is in disterbance, there will be mental disorder. Since blood contains fluid,it can moisten the viscera and the body. When the fluid flows out of the vessels,it moistens the orifices and lubricate the joints.

The basic concept of body fluid Body fluids refer to the different kinds of physiological fluids found in the body, including fluids in the organs and tissues, gastric fluid, intestinal fluid, semen and tears. Classified as one of the fundamental substances, body fluids are essential to life‘s activities . Body fluid is also a component of blood when it flows inside the vessels. However, body fluid also flows outside the vessels in the viscera and the body. If secreting or excreting from the five sensory organs and the nine orifices,body fluid becomes urine,sweating,tears,snivel,saliva and drool,ect. (若津液从五官九窍中分泌或排泄出来就成为了尿、汗、泪、涕、唾、涎)

Functions of Body Fluids 1. Moistening and nourishing Body fluids are mainly responsible for providing moisture and nourishment to the tissues. When distributed to the surface of the body, body fluids moisten the skin and hair and maintain the smooth and elastic texture of the skin. Body fluids also moisten, nourish and protect different orifices in the body. For example, body fluids allow the eyes to blink smoothly, the nasal cavity to maintain an open airway without blockage and the lips and mouth to remain moist without becoming dry. Internal body fluids also penetrate different organs, tissues and even bone marrow to provide moisture and nourishment. The spinal cord and brain are examples of organs surrounded by body fluid that protects and nourishes them.

Functions of Body Fluids 2 the transformation of blood body fluid not only flows outside the vessels,but also inside the vessels to participate in the production of blood. Blood is composed of two parts:body fluid and the nutrient qi. If body fluid is insufficent, the production of blood will be reduced,leading to blood deficiency. Disharmony of body fluids is manifested in two ways. When body fluids can no longer nourish and provide moisture to the body, symptoms such as dry skin, flaccid muscles, brittle hair, dry eyes, parched lips and a dry nose or throat occur. When there is dysfunction of distribution or excretion of body fluids symptoms can present as swollen eyelids, edema (retention of fluid in the tissues), obesity or other conditions

小 结

Connections Between Qi, Blood and Body Fluids Connection between Qi and Blood The relation of Qi and Blood can be generalized as having two aspects: Qi as the commander of Blood, and Blood as the mother of Qi. As the commander of Blood, Qi has three main functions. First, generating Blood. This means that the generation of Blood depends on Qi's activities for its production. Blood is composed of Body Fluids and Nutritive Qi, which is produced by food through the functional activities of Spleen Qi and Stomach Qi. During this process, it is Qi's activities that transform the food into food Essence, then into Nutritive Qi and Body Fluids and ending in the formation of Blood. Without Qi's activities, there would be no Blood. So Qi can generate Blood. When Qi is vigorous, it can generate adequate Blood. On the other hand, Deficiency of Qi will cause Blood Deficiency due to decline of its action of generating Blood. Clinically, Qi-invigorating drug are often added to Blood-nourishing formulas to promote the generation of Biood.

Connections Between Qi, Blood and Body Fluids Second, propelling the circulation of Blood. This means that Blood, a Yin substance which is motionless in nature, depends on Qi for its movement. To be exact, Heart Qi moves Blood by maintaining the beating of the Heart, Lung Qi pushes Blood outward through its dispersing effect and sends down Blood through its descending effect, and the Liver's dispersing and discharging effects help to regulate the free flow of Blood. When Qi is deficient and hasn't enough power to propel, the Blood flow will become sluggish or Blood Stasis will occur. If Qi's ascent, descent, or entry and exit movements are destroyed, Blood Flow will also be disturbed. For example, adverse upward flow of Qi will cause Blood to flow upward excessively, giving rise to distending pain of the head, blood, shot eyes, red face, or even hematemesis and coma. Therefore, Blood flow disorders are usually treated both with drugs regulating Blood and drugs regulating flow of Qi. Third, controlling the flow of Blood. This means that Qi functions to keep Blood flowing within the vessels to prevent extravasation, which is mainly performed by Spleen Qi. If Qi fails to control Blood flow, various kinds of bleeding will occur. Clinically, bleeding due to Qi Deficiency must be treated by strengthening the Spleen so that Blood flow can be controlled. Blood as the mother of Qi has two meanings: Qi attaching to Blood and Blood supplying Qi. Qi is a vigorous substance and prone to flee easily, so it must attach itself to Blood so that it can reach all of its distribution points to perform its normal function. This is also a manifestation of mutual restriction of Yin and Yang, or the motionless nature of Blood restricting the moving nature of Qi. By Blood supplying Qi is meant that Blood nourishes Qi or serves as the material basis of Qi. Clinically, a severe hemorrhage often gives rise to escape of Qi due to the failure of Blood to carry Qi, and Blood Deficiency often leads to Qi Deficiency.

Connections Between Qi, Blood and Body Fluids Relationship between Qi and Body Flulds The relations of Qi and Body Fluids is very similar to those of Qi and Blood. The generation, distribution and discharge of Body Fiuids depend on Qi and its activities. On the other hand, Qi also relies on Body Fluids to be carried, and Body Fluids are where Qi exists, moves and changes. Qi can generate Body Fluids. Body Fluids comes from food and drink, which are transformed into both refined and waste material through the activities of the Spleen and Stomach. The liquid that has been refined, or Body Fluids, is then distributed to each part of the body by the Spleen. When the Spleen and the Stomach function properly, Body Fluids can be adequately generated on the other hand, Deficiency of Spleen Qi or Stomach Qi will lead to inadequate formation of Body Fluids, causing Deficiency of both Qi and Yin Fluids. Qi can distribute and transform Body Fluids. Body Fluids are substantial and motionless in nature. So their distribution and discharge depend on the propulsion of Qi and the activities of Qi. As a result of the ascent, descent, and entry and exit movements of Qi of the Spleen, the Lung and the Kidney, Body Fluids are distributed all over the body to perform their moistening effect. All the metabolized Body Fluids must be transformed into sweat, urine or steam to be discharged, so the transforming effect of Qi plays an important part in the discharge of Body Fluids. Failure of Qi to propel and transform due to its Deficiency or to stagnation of Qi can give rise to retention of Body Fluids, leading to edema, Damp or Phlegm, which is known as inability of Qi to propel and transform Body Fluids.

Connections Between Qi, Blood and Body Fluids Qi can control Body Fluids. This means that Qi can control the flow and discharge of Body Fluids to prevent their excessive loss. For example, Defensive Qi can prevent excessive sweating by controlling the closing and opening movements of the sweat pores. If Defensive Qi is deficient, spontaneous sweating will occur as a result; Kidney Qi controls the opening and closing of the Bladder, so Deficiency of Kidney Qi often leads to profuse and frequent urine, enuresis and incontinence of urine. For such cases, drugs consolidating Qi must be adopted to obtain effectiveness. Body Fluids carry Qi. Qi is also attached to Body Fluids. When too much Body Fluids are lost, Qi will escape. Excessive vomiting or diarrhea, for example, will impair Qi, leading to Deficiency of Qi, which is often accompanied by lassitude, a symptom of Qi Deficiency

Connections Between Qi, Blood and Body Fluids Relationship between Blood and Body Fluids Blood and Body Fluids are from the same source and their functions are similar. So they can be transformed into each other and are closely related to each other. Both Blood and Body Fluids are derived from food Essence, hence they are said to have "a common source'. Body Fluids are an important component of Blood, and Body Fluids in the vessels can go out of the vessels to make up Body Fluids of the body and vice versa, so Blood and Body Fluids usually influence each other under pathologic conditions. When excessive loss of Blood occurs, Body Fluids that are out of the vessels can enter the vessels to compensate for the loss in the same way, when there is excessive consumption of Body Fluids, the Fluids in the vessels can also go out of the vessels to increase those Body Fluids. Therefore, for patients with excessive bleeding, diaphoretic should be avoided; while for patients with Deficiency of Body Fluids, the practice of removing Blood Stasis with drastic drugs is not indicated.
