System: Blood Pressure
Regulation and Key Organs-
Questions with Correct Answers
(VERIFIED)
What is the primary function of the renin-angiotensin-aldosterone system (RAAS)?—
ANSWER--To regulate blood volume, electrolyte balance, and systemic vascular resistance.
How does the RAAS affect blood pressure?—ANSWER--By increasing sodium reabsorption,
water retention, and vascular tone.
What enzyme is produced by the kidneys in the RAAS?—ANSWER--Renin
What is the role of angiotensin II in the RAAS?—ANSWER--It mediates blood pressure and
volume regulation and stimulates aldosterone secretion.
What hormone is secreted by the adrenal cortex in the RAAS?—ANSWER--Aldosterone
What triggers the release of renin from the kidneys?—ANSWER--Decreased renal blood flow.
What is angiotensinogen and where is it produced?—ANSWER--A protein made and
released by the liver that is split by renin into angiotensin I.
