The kidneys maintain homeostasis by manipulating the composition of a certain substance, in this way the kidneys can regulate things like body acid-base balance and fluid electrolytes balance. What is the substance that the kidneys modify?
The kidneys maintain homeostasis by manipulating the composition of a certain substance, in this way the kidneys can regulate things like body acid-base balance and fluid electrolytes balance. What is the substance that the kidneys modify?

The kidney must filter enough water and electrolytes out of the blood to equal the amount that is being put into it from other sources. For example, the levels of certain substances in plasma must be maintained within specific narrow concentration limits for health and life to continue. Which of the following is one of these substances?
