三、水、钠、氯代谢 (一)水的生理功用水不仅是组成人体的主要成分,而且具有调节体温,运输物质,促进物质代谢(水是良好的溶剂),滑润脏器(脏器间,关节腔内液体)等作用。 (二)水的动态平衡水的动态平衡靠来源与去路来维持。水的来源有三:①饮料,如饮水和食入流质,平均每日约1,200毫升; ②食物中的水,包括固体、半固体食物中的水,约1,000毫升;③生物氧化,即物质代谢脱下来的氢与氧结合生成的水,
Third, the water, sodium, chlorine metabolism (A) the physiological function of water Water is not only composed of the main components of the human body, but also has the regulation of body temperature, transport substances, promote material metabolism (water is a good solvent) , Joint cavity fluid) and so on. (B) the dynamic balance of water Dynamic balance of water by sources and ways to maintain. There are three sources of water: ① drinks, such as drinking water and feed liquid, an average of about 1,200 ml per day; ② food water, including solid, semi-solid food water, about 1,000 ml; ③ biological oxidation, Of hydrogen and oxygen generated by the combination of water,
