Compensatory mechanism in acute hemorrhage?

Ans. is 'c' i.e., Increased hea rate Compensatory mechanisms in acute hemorrhage In acute hemorrhage there is compensatory sympathetic stimulation which causes :? 1) Generalized vasoconstriction with increased total peripheral resistance (TFR). 2) Increased hea rate (tachycardia). 3) Increased cardiac contractility. 4) Increased renin release causing sodium and water retention through RAA system. 5) Shift of fluid from intracellular and interstitial space into vascular space.
