Question

Quizplus · Accepted Answer

Aldosterone promotes sodium retention in the kidneys, which leads to an increase in blood volume and blood pressure. It is secreted in response to low blood pressure or decreased sodium levels in the body. It does not increase the concentration of sodium in urine and does not primarily function in pH regulation.
