What converts Angiotensin I into Angiotensin II?
Angiotensin converting enzyme
What converts the enzyme Angiotensinogen into Angiotensin I?
Renin
Angiotensin II causes:
Adrenal gland to secrete Aldosterone
What does Aldosterone do?
Increases collecting duct permeability
Decrease in extracellular pressure near _______ causes _________ to release the hormone _______
