Renin-Angiotensin-Aldosterone System (RAAS) and ADH in Blood Pressure Regulation
Exam Questions and Correct Answers 100% Verified Graded A+
What is the primary function of the Renin-Angiotensin-Aldosterone System (RAAS)? -
To regulate blood pressure, fluid balance, and systemic vascular resistance in the body.
What triggers the secretion of renin? - Low blood pressure, low sodium levels, or
sympathetic nervous system activation.
What does renin convert angiotensinogen into? - Angiotensin I.
Where is angiotensin I converted into angiotensin II? - Primarily in the lungs by the
angiotensin-converting enzyme (ACE).
What is the active form of the hormone in the RAAS? - Angiotensin II.
What effect does angiotensin II have on blood vessels? - It causes vasoconstriction, which
increases blood pressure.
What hormone does angiotensin II stimulate the release of from the adrenal glands? -
Aldosterone.
What is the role of aldosterone in the body? - It promotes sodium and water retention by
the kidneys, increasing blood volume and pressure.
