Question

aldosterone from the adrenal cortex causes sodium ions to be ________ and potassium ions to be ________.

multiple choice

conserved, conserved
excreted, excreted
excreted; conserved
conserved, excreted

Explanation:

Aldosterone is a hormone from the adrenal cortex. Its main function is to regulate sodium and potassium levels. It acts on the kidneys. It causes the kidneys to re - absorb sodium ions (so sodium is conserved) and secrete (excrete) potassium ions. This helps in maintaining electrolyte balance, blood volume, and blood pressure.

Answer:

Aldosterone from the adrenal cortex causes sodium ions to be conserved and potassium ions to be excreted. So the correct option is "conserved, excreted".
