Renin-Angiotensin-Aldosterone System Exam Questions with
Correct Answers (Grade A+)
Question 1: renin-angiotensin-aldosterone system
Answer: a hormone cascade that increases blood pressure and blood volume
Question 2: renin
Answer: An enzyme secreted by the juxtaglomerular cells when blood pressure or blood volume decreases.
Renin converts angiotensinogen to angiotensin I.
Question 3: angiotensinogen
Answer: a plasma protein produced by the liver. Renin converts angiotensinogen into angiotensin 1.
Angiotensinogen literally means "vessel tensing generator"
Question 4: angiotensin converting enzyme (ACE)
Answer: converts angiotensin I to angiotensin II
Question 5: ACE inhibitors
Answer: "PRIL" Captopril, Enalapril, Afosiopril Antihypertensive. Blocks ACE in lungs from converting
angiotensin I to angiotensin II (powerful vasoconstrictor). Decreases BP, Decreased Aldosterone secretions,
Sodium and fluid loss.
Question 6: aldosterone
Answer: Steroid hormone from the adrenal cortex that stimulates the kidney to retain sodium. Water follows
salt so blood volume goes up which then raises blood pressure.
Question 7: Angiotensin II
Answer: 1. potent vasoconstrictor of arterioles 2. stimulates aldosterone release from adrenal cortex 3.
stimulates vasopressin (ADH) release from the posterior pituitary gland. RAISES BLOOD PRESSURE
Question 8: Antidiuretic hormone (ADH, vasopressin)
Answer: released from posterior pituitary gland; causes kidneys to reabsorb more water. This increases
blood volume which increases blood pressure.
