Renin-Angiotensin System Flashcards
1
Q
What does angiotensin-II do?
A
Volume homeostasis and Cardiovascular control
2
Q
What are the angiotensin-II dependent mechanisms?
A
Hemorrage, Vomiting, Diarrhea –> Decrease extracellular fluid volume and blood pressure –> Increased production of Angiotensin-II –> Direct and Indirect effects of Angiotensin-II to restore blood volume and pressure
3
Q
Regulation of Ang II synthesis occurs at: (2)
A
(1) Renin (primary control point, rate-limiting enzyme)
2) Angiotensinogen (stimulated by cortisol, secretion of which is increased following a fall in ECF
