Renin-Angiotensin-Aldosterone System: Blood Pressure Regulation
and Key Organs Questions with Correct Answers (Grade A+)
Question 1: What is the primary function of the renin-angiotensin-aldosterone system (RAAS)?
Answer: To regulate blood volume, electrolyte balance, and systemic vascular resistance.
Question 2: How does the RAAS affect blood pressure?
Answer: By increasing sodium reabsorption, water retention, and vascular tone.
Question 3: What enzyme is produced by the kidneys in the RAAS?
Answer: Renin
Question 4: What is the role of angiotensin II in the RAAS?
Answer: It mediates blood pressure and volume regulation and stimulates aldosterone secretion.
Question 5: What hormone is secreted by the adrenal cortex in the RAAS?
Answer: Aldosterone
Question 6: What triggers the release of renin from the kidneys?
Answer: Decreased renal blood flow.
Question 7: 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.
Question 8: What is the function of angiotensin- converting enzyme (ACE)?
Answer: To convert angiotensin I into angiotensin II in the lungs.
Question 9: What effect does angiotensin II have on arterioles?
Answer: It causes the walls of arterioles to constrict, increasing blood pressure.
Question 10: Which gland releases antidiuretic hormone (ADH) in response to angiotensin II?
