Select the Correct Statement Related to the Renin-Angiotensin-Aldosterone (RAA) Mechanism

question 15

Multiple Choice

Select the correct statement related to the renin-angiotensin-aldosterone (RAA) mechanism.

• A) A drop in systemic blood pressure or a decrease in renal blood flow stimulates the release of renin from the kidneys. Renin initiates reactions that lead to the formation of angiotensin II. Angiotensin II causes vasoconstriction and the release of aldosterone (sodium retention) and ADH (water retention). These actions normally function to maintain normal blood pressure and blood volume.
• B) An increase in systemic blood pressure or an increase in renal blood flow stimulates the release of renin from the kidneys. Renin initiates reactions that lead to the formation of angiotensin II. Angiotensin II causes vasoconstriction and the release of aldosterone (sodium retention) and ADH (water retention). These actions normally function to maintain normal blood pressure and blood volume.
• C) A drop in systemic blood pressure or a decrease in renal blood flow stimulates the release of renin from the kidneys. Renin initiates reactions that lead to the formation of angiotensin II. Angiotensin II causes vasodilation and the release of aldosteone (sodium retention) and ADH (water retention). These actions normally function to maintain normal blood pressure and blood volume.
• D) None of these are correct.
