in CCF the perfusion of renal tissue decreases so RAA system works,ADH increases :arrow: extracelluler fluid volume increases :arrow: incresed sytemic venous pressure :arrow: intravascular fluid moves to the extravascular compartman (hepatomegali, pulmoner congestion,assit) :arrow: HTC inc. :!: decreased perfusion :arrow: erytropoetin syntesis increases :arrow: HTC inc. :idea: İnc. HTC :arrow: dec. ESR because RBC are negative and they try to be away from each other :wink: İ hope this helps..
