生理习题名词解释（Explanation of physiological exercises nouns） Noun interpretation Compliance with lung compliance is an indicator of the degree of difficulty in lung expansion. It refers to changes in lung volume caused by changes in lung pressure across units, and is inverse relation to pulmonary elastic resistance. Pulmonary surfactant pulmonary surfactant is the material secreted by alveolar type two palmitoyl lecithin as the main ingredient, a single molecular layer distribution in the liquid gas interface, the density decreases with the expansion of the alveoli, adjust the surface tension. Breathing and breathing work refers to the work done by the respiratory muscle to overcome the elastic resistance and the non - elastic resistance of the pulmonary ventilation. Usually, the pressure changes per unit time are calculated by multiplying the volume change. In calm breathing, 2/3 is used to overcome elastic resistance, and 1/3 is used to overcome inelastic resistance The inspiratory reserve volume, the inspiratory reserve volume, also called the inspiratory volume, means the amount of air that can be inhaled at the end of the calm and forced air. Normal adults aboutl. Functional residual gas refers to the end of calm and expiratory, and the volume remaining in the lung is the sum of residual volume and supplementary expiratory volume. The role of excessive changes in alveolar oxygen and partial pressure of carbon dioxide during buffering. Alveolar ventilation volume per minute ventilation volume / maximum ventilation volume * 100% normal value 93% The ventilatory reserve was 100 percent more than the 100 percent ventilatory reserve (the maximum ventilation rate was one time after maximal inhalation, and the maximum expiratory rate was calculated. At the same time, the volume of exhaled air at first, second, third seconds was calculated as the percentage of lung capacity. The normal subjects were 83%, 96% and 99% respectively. A dynamic index that reflects lung
