Question Answer
Aldosterone TRIGGERED BY:Angiotensin II
Aldosterone SECRETED BY:Adrenal Cortex
Aldosterone TARGET:Kidneys (Distal convoluted tubule & collecting duct)
Aldosterone FUNCTION:Increase salt reabsorption of distal convoluted tubule & collecting duct
ANP TRIGGERD BY:When the heart stretches due to elevated blood pressure
ANP SECRETED BY: Heart
ANP TARGET:Kidneys
ANP FUNCTION:Decrease water & salt reabsorption
Angiotensin I SECRETED BY:Liver
CONVERTS Angiotensin I --> Angiotensin II: Renin
Angiotensin II TARGETS: 1) Posterior Pituitary Gland --> release ADH; 2) Adrenal Cortex --> release Aldosterone
ADH TRIGGERED BY:Angiotensin II
ADH SECRETED BY:Posterior Pituitary Gland
ADH TARGET: Kidneys
ADH FUNCTION: Increase water reabsorption at distal convoluted tubule & collecting duct
