Question

water retention
which hormones work synergistically to retain water?
antidiuretic hormone (adh) and aldosterone
aldosterone and cortisol
aldosterone and atrial natriuretic peptide (anp)
atrial natriuretic peptide (anp) and antidiuretic hormone (adh)

Explanation:

• Antidiuretic hormone (ADH) acts on the kidneys' collecting ducts to increase water re - absorption.
• Aldosterone promotes sodium re - absorption. When sodium is re - absorbed, water follows osmotically.
• Cortisol mainly affects metabolism and stress response, not directly water retention in a synergistic way with the others.
• Atrial natriuretic peptide (ANP) promotes sodium and water excretion, so it does not work synergistically with hormones for water retention.

Answer:

Antidiuretic hormone (ADH) and aldosterone.
