Pathophysiology Hypertension
Kidney release RENIN into the bloodstream
RENIN helps convert angiotensin I in liver
Angiotensin I is converted to angiotensin II ( a potent vasoconstrictor) in lungs
Angiotensin II
Aldosterone: Cause NA and water retension
Retained NA and Water Increased Blood Volume
Arteriolar constriction Increased Peripheral vascular resistance
Increased Blood pressure and vascular resistance to hypertension
