Question

multiple choice question
which hormone decreases blood pressure?

epinephrine
angiotensin ii
aldosterone
antidiuretic hormone (adh)
atrial natriuretic peptide (anp)

Explanation:

To determine which hormone decreases blood pressure, we analyze each option:

• Epinephrine: Increases heart rate and blood pressure.
• Angiotensin II: Increases blood pressure by vasoconstriction and aldosterone release.
• Aldosterone: Increases blood volume (and thus pressure) by promoting sodium and water reabsorption.
• Antidiuretic hormone (ADH): Increases blood volume (and pressure) by reabsorbing water.
• Atrial natriuretic peptide (ANP): Secreted by the heart, it promotes sodium and water excretion, reducing blood volume and thus decreasing blood pressure.

Answer:

E. Atrial natriuretic peptide (ANP)
