Question

Arrange in the order that represents the negative feedback mechanism on the RAAS loop.

• A. Renin decreases
• B. Renin stops
• C. $\mathrm{High}\mathrm{Angiotensin}\mathrm{II}$
• D. High BP

Answer 1

The body senses increasing levels of angiotensin II, and this by itself suppresses renin release. This is called an inhibitory feedback loop. As angiotensin II increases, renin decreases, which means angiotensin II also decreases since it depends on renin for its production.
