The Renin-Angiotensin-Aldosterone System (RAAS) Questions with
Verified Answers (Correct Update)
Question 1: (VERIFIED)
when your blood pressure drops baroreceptors are going to detect that. And you're going to
have
an increase in
Answer: sympathetic nervous system activity.
Question 2: But that increase in sympathetic activation causes the kidneys to release a chemical
called
Answer: Renin
Question 3: Renin
Answer: it's an enzyme, and it's going to convert angiotensinogen into something called
angiotensin I.
Question 4: Renin from the kidneys converts angiotensinogen into
Answer: angiotensin I
Question 5: And then angiotensin I needs to be converted into angiotensin II. And that happens
through an
enzyme called
Answer: angiotensin converting enzyme ( ACE)
Question 6: This ACE enzyme actually comes from the
Answer: lungs
Question 7: This ACE enzyme converts angiotensin I into angiotensin II. And then angiotensin
II can create
all of these
Answer: four different pathways in order to bring our blood pressure back up.
Question 8: When blood pressure drops, baroreceptors pressure detectors can detect that
Answer: change in
pressure

, Question 9: Your sympathetic nervous system turns on to try to increase your
Answer: blood pressure
Question 10: By increasing sympathetic nervous system activity that cues the kidneys to release
this
chemical called
Answer: Renin
Question 11: Renin is going to convert angiotensinogen into angiotensin I. Then we have another
enzyme
from the lungs called
Answer: ACE that converts angiotensin I into angiotensin Ii
Question 12: So on the short term, what this is going to do. angiotensin II can act as a
Answer: vasoconstrictor
Question 13: Vasoconstriction is short term control. Changing blood volume is a
Answer: long term control
Question 14: Angiotensin II is going to cause us to release more ADH from the
Answer: posterior pituitary
Question 15: ADH comes from the posterior pituitary. And that causes the kidneys to
Answer: reabsorb more
water.
Question 16: The more water we are reabsorbing, the more water we're putting back into the
blood is going to
Answer: increase blood volume and therefore increase blood pressure
Question 17: Angiotensin II is going to cause our adrenal cortex to release
Answer: more aldosterone
