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:
Correct Answer:
BNP decreases blood pressure by causing vasodilation and promoting sodium and water excretion.
Rationale:
🩸 B-type natriuretic peptide (BNP) is released by the ventricles in response to fluid overload or increased pressure.
🩸 It promotes vasodilation and excretion of sodium and water, thereby lowering blood pressure.
🩸 Elevated BNP is a key marker for heart failure, aiding in diagnosis and management.
🩸 BNP counteracts the RAAS system, making it protective in volume overload conditions.
