The delicacy of Zang-fu organs and in Physics and Qi
The Zang-fu organs to refer to both bodies and the Zang Fu organs. Delicacy weakness of the responsibility for the attack and tenderness. The physical refers to the configuration of the human body such as members, the skeleton, musculature, gasoline, blood and body fluids.
Qi refers to physiological functional activities, such as the Qi of the lung, spleen and kidney Qi Qi. Delicacy of the Zang Fu organs and under-development of physics and qi means that during childhood, the morphological development and physiological functions are immature and imperfect, and that the development and functions of the viscera are insufficient. Since the physical materials of the body relate to the yin and the functioning of the organization's activities relate yang, the ancient physicians summarized the physiological characteristics of children as sub-yin and yang.
The idea that the viscera of children are vulnerable and the body of infants is underdeveloped is characterized by sensitivity of the muscles and skin, streaks in bulk, lack of qi and blood, weakness of the lungs and spleen, kidney qi, half-hearted commitment and fragile bones and muscles. For example, from birth to childhood, children are marked by the large head, thin neck, above and short below. During the period of one year and a half, children play a role metopism, thin skin and soft, loose interstitial muscle striations, and yellow hair, the responsibility of sweating during sleep, short of voice crying and instantaneous changes in emotions. The functions of two bodies of the five Zang and six Fu organs are underdeveloped, particularly the lungs, spleen and kidneys.
Constant lack of lung
The lung governs qi circulating all through the body. It is linked to skin, hair and stripes outside. If the lung is delicate, defensive qi is not, making it easier to be attacked by exogenous pathogens. The lung depends on the rate of nutrient supply. If the spleen and stomach are strong, the defensive qi is consolidated. However, the rate of children tends to be low in the functions, so the Qi of the lung in children is generally insufficient.
