E. secrete erythropoietin

Answer: A. conserve sodium and excrete potassium

Aldosterone is another hormone that is produced from the adrenal cortex and its main function is to balance the movement of body water and its associated minerals. In detail, aldosterone is involved in the action of controlling and maintaining the levels of sodium and potassium ions within the body cells and outside the body through a process that takes place in the kidneys’ area. Any circumstances under which the levels of aldosterone are high or have been elevated brings into effect the slice of the kidneys to retain more number of sodium ions from the filtered blood as well as excrete more number of potassium ions from the formula of urine. This makes it easier in maintaining the concentration of Sodium and potassium within the blood stream for to perform some functions that include contraction of muscles, transmission of nerve impulses, and regulation of blood pressure.
