Part A Explain how baroreceptor reflexes will respond to the decrease in CO and MAP at the onset of heart failure. Include the pathways and mechanisms of actions involved including neurotransmitters, hormones, receptors, etc. Part B Explain how increased fluid retentions occurs by describing the pathway and mechanism, and why this occurs meaning how this attempts to compensate for the decrease in CO and MAP. Part C Explain why increased venous pressure causes edema using blood vessels and Starling forces. Part D Why are diuretics often prescribed to heart failure patients?
