Practice Question

Which of the following best describes the primary physiological role of B-type natriuretic peptide (BNP) in the regulation of cardiovascular function?

Answer Choices:

A. BNP promotes the synthesis of angiotensin II to enhance fluid retention and increase blood pressure.

B. BNP increases heart rate and cardiac contractility to enhance cardiac output.

C. BNP increases blood pressure by causing vasoconstriction and stimulating aldosterone release.

D. BNP decreases blood pressure by causing vasodilation and promoting sodium and water excretion. ✓ Correct Answer

Correct Answer:

BNP decreases blood pressure by causing vasodilation and promoting sodium and water excretion.

Rationale:

❤️BNP is released in response to ventricular stretch and volume overload.

🩸It promotes vasodilation of blood vessels, reducing systemic vascular resistance and lowering blood pressure.

💧BNP increases natriuresis and diuresis by inhibiting sodium reabsorption in the kidneys and suppressing aldosterone release.

⚖️These actions collectively decrease blood volume and cardiac workload, counteracting the renin–angiotensin–aldosterone system.

📌Core Message

BNP lowers blood pressure by dilating vessels and increasing sodium and water excretion.
