  62. How is the renin angiotensin system related to hypovolemia and hypotension?
    when BP and fluid are low renin is release and creates angiotensin 1 which the body automaticly converts to angiotensin 2 (BAD!!) so an ACE inhibitor is given which prevents angiotensin 1 from converting to angiotensin 2
