Explain RAAS Renin-angiotensin-aldosterone system 1. Reduce blood flow causes kidneys to release renin > produce angiotensin I > converts angiotensin I to angiotensin II > vasoconstriction > release aldosterone > kidneys conserve sodium and water > Result less water lost in urine and blood pressure maintained. DKA increased anion gap, decreased HCO3 How do kidneys compensate for alkalosis retain H and excrete HCO3 Untreated acidosis leads to an increase in which electrolyte?
