Type of angiotensin
|
Angiotensin I
Angiotensin II (most biologically active) Angiotensin III |
|
|
Actions of angiotensin II
|
Vasoconstriction
Release of aldosterone Alteration of cardiac and vascular structure |
|
|
Actions of aldosterone – released from the adrenal medulla
|
Regulation of blood volume and blood pressure
Pathologic cardiovascular effects – includes cardiac remodeling and fibrosis |
|
|
Formation of angiotensin II by renin and angiotensin-converting enzyme (ACE)
|
Renin
Catalyzes the formation of angiotensin I from angiotensinogen Regulation of renin release – is released into bloodstream from kidneys via low [BP, blood volume, Na Conc, renal perfusion] Angiotensin-converting enzyme (kinase II) Catalyzes the conversion of angiotensin I (inactive) to angiotensin II (highly active |
