Loss of a large quantity of blood due to hemorrhage provokes compensatory and decompensatory physiological changes. Consider the following statements: A. Peripheral chemoreceptors are stimulated when arterial blood pressure falls below 60 mm Hg. B. Cardiovascular centers in the brain stem become depressed in severe hypotension due to blood loss. C. The mononuclear phagocytic system becomes depressed during hemorrhagic hypotension. D. Renin is secreted from the juxtaglomerular apparatus in hemorrhagic hypotension. E. Interstitial fluid is drawn into circulation due to lower hydrostatic pressure in capillaries. Which of the following options describes ONLY the decompensatory mechanisms?
