"Blood" is the red liquid circulating in the body's veins and vessels; it helps carry nourishment throughout the entire body. Similarly, "body fluids" are a general term for all the water contained in the body and necessary for life.
Qi is attributed to Yang, because of it's mobility and warming function; Blood and body fluids are ascribed to Yin because they are motionless; their purpose is to both nourish and moisten the human body.
Explanation of Qi
Qi was originally of philosophic perception. The ancients believed that the world changes and that things in the world can transform from one to another. Consequently, when they tried explaining the world with through common substance, they determined that a substance must have two properties, invisibility and motion.
Invisible was determined as having no certain shape and could create various kinds of things. Air, the original meaning of Qi, is an example of such a substance--it cannot be seen but its movement as wind, can be felt. This then meant that the most basic substances found in the world, its movement and change, explained the creation, development and change of all things in the world.
Thus Qi -- blood, is the most fundamental substance in the construction of the human body and in the maintenance of life activities. Any significant matter can be regarded as a special process of the movement of Qi, and life.
Man depends on nature for his production and growth and must observe the common laws of the world. As everything in the world comes from the interaction of Heaven Qi and Earth Qi, man must breathe to absorb Heaven Qi and eat to absorb Earth Qi. The food Essence transformed and transported by the spleen must be sent up to the lung to combine with fresh air to produce the nutrients necessary for man's life activities.
Formation of Qi
The human body develops from the combination of three kinds of Qi:
Primordial Qi is originates from the congenital essence of the parents; it is the primary substance to produce an embryo. It forms the source of the human body and its life activities. Without congenital essence there can be no human body. After birth, the congenital essence is stored in the kidney to promote development and to control the reproductive activity of the body. Fresh air Qi is inhaled by the lung after birth; it is the main source of Qi of the human body. The refined food essence is generated by food which is taken in after birth. It is distributed all over the body to produce nutrients, Qi and Blood via the actions of the spleen and stomach.
