Which of the Following Hormones Stimulates Increased Urinary Excretion of Na⁺

Question

Which of the following hormones stimulates increased urinary excretion of Na⁺? A)norepinephrine B)aldosterone C)antidiuretic hormone D)atrial natriuretic peptide E)angiotensin II

Accepted Answer

Atrial natriuretic peptide (ANP) stimulates increased urinary excretion of sodium (Na+), chloride (Cl-), and phosphate (PO43-), while simultaneously decreasing the reabsorption of these ions in the kidney tubules. This results in an increase in urine volume and decreased blood volume and blood pressure. ANP is released from the heart in response to increased atrial pressure, which is often caused by an increase in blood volume.
