The RAAS System is a cascade of reaction that take place in the human body whenever the systolic blood pressure drop as the body attempt to restore normal blood pressure. When blood pressure falls, the kidney experience hypoxia which will trigger the release of renin (enzyme) from the juxtaglomerular cells of the kidney into the blood stream. Blood reach in renin will convert inactive angiotensinogen (angiotensin precursor that is produce in the liver) into active angiotensin I. When blood reach in angiotensin I perfuse the lungs, this will trigger the release of angiotensin converting enzyme from the lung which will convert angiotensin I to angiotensin II. Angiotensin II act (1) by constricting blood vessels (arteries), (ii) causes the release of aldosterone from adrenal gland atop the kidney and vasopressin from posterior pituitary gland which act on the kidneys to excrete potassium and retain sodium. The retention of sodium will in turn retain water - this will increase blood volume. The increase blood volume together with the vasoconstriction will in turn increase blood pressure.
