Quizplus · Accepted Answer

Salt balance in humans primarily depends upon control of Na+ output by the kidneys. The kidneys play a vital role in maintaining salt balance by regulating the amount of Na+ that is excreted from the body through urine. The body also has mechanisms to regulate salt intake, but it is not the primary factor in maintaining salt balance.
