What triggers the release of Renin into the bloodstream?
What triggers the release of Renin into the bloodstream?
- An increase in Angiotensin II levels
- A decrease in sodium levels in the blood (correct)
- An increase in blood pressure
- A decrease in Aldosterone levels
What is the primary function of the Renin-Angiotensin-Aldosterone System (RAAS)?
What is the primary function of the Renin-Angiotensin-Aldosterone System (RAAS)?
- To convert Angiotensin I to Angiotensin II
- To filter waste and excess water from the blood
- To release Aldosterone into the bloodstream
- To regulate blood pressure and fluid balance (correct)
What is the effect of Angiotensin II on blood vessels?
What is the effect of Angiotensin II on blood vessels?
- It has no effect on blood vessels
- It promotes the reabsorption of sodium in the kidneys
- It causes blood vessels to constrict, increasing blood pressure (correct)
- It causes blood vessels to dilate, decreasing blood pressure

What triggers renin release?
What triggers renin release?
A decrease in sodium levels in the blood triggers the release of renin.
What is the function of the RAAS?
What is the function of the RAAS?
RAAS regulates blood pressure and fluid balance by controlling sodium and water levels in the body.
How does Angiotensin II affect blood vessels?
How does Angiotensin II affect blood vessels?
Angiotensin II constricts blood vessels, making them narrower and increasing blood pressure.
