|
Angiotensin II |
Is a powerful vasoconscrictor that is produced by Angiotensinogen (cleaved by renin) |
|
|
|
Renin |
Released from juxtamedullary cells in the kidney .
Excellent at finding a drop in BP.
Cleaves Angiotensinogen (from liver) which turns into Angiotensin 1 |
|
|
|
Angiotensin I |
Once activated it converts to Angiotensin II , via ACE (Angiotensin converting enzyme) |
|
|
|
Angiotensin II functions |
has 4 fxns
Powerful vasoconscrictor that increases BP
Secreted by adrenal cortex . Aldosterone reabsorbs NA as NA moves into blood stream water follows and so blood volume increase and BP increase
Stimulates release of ADH which also promotes water absorption
Stimulates thirst reflex
|
|
|
|
Ace |
Released from lungs |
|
|
|
Angiotensinogen |
Produced by liver and in circulating blood |
|
|
|
Atrial natriuretic peptide (ANP) |
Released by hearts atria . High BP stretches atrial walls which Stimulates the release of ANP. ANP inhibits production of ADH from the posterior pituitary gland . And also causes Natruiresis (Inc loss of sodium in the urine) |

Aldosterone Secreted by ? |
Adrenal cortex |
