酸碱平衡紊乱人体的体液环境需有适宜的酸碱度才能维持正常的代谢和生理功能。这个适宜的酸碱度是 pH 7.36～7.44,为一变动范围狭窄的弱碱性环境。人体在代谢过程中不断产生酸性物质,如碳酸(挥发酸)及乳酸、酮体、硫酸、磷酸等固定酸(非挥发酸),也会经常摄取酸性或碱性食物。但通过缓冲系统以及肺、肾的调 Acid-base balance disorders The body’s fluid environment requires appropriate pH to maintain normal metabolism and physiological functions. This suitable pH is pH 7.36 ~ 7.44, a narrow range of changes in a weak alkaline environment. The body constantly produce acidic substances in the metabolism, such as carbonic acid (volatile acid) and lactic acid, ketone body, sulfuric acid, phosphoric acid and other fixed acids (non-volatile acids), will often take acidic or alkaline foods. But through the buffer system and lung, kidney tone
