Under normal physiologic conditions, the kidney is the organ chiefly responsible for the maintenance of potassium balance. Knowledge of the physiologic properties of the distal nephron that affect potassium secretion allows for a better understanding of how potassium excretion can be modulated. This article will review the normal renal handling of potassium and the factors responsible for maintaining potassium balance.
在正常生理条件下，肾脏是主要负责维持钾平衡的器官。了解影响钾分泌的远端肾单位的生理特性有助于更好地理解钾排泄是如何被调节的。本文将综述肾脏对钾的正常处理以及维持钾平衡的相关因素。
