Which outcome predictably affects the cardiovascular system upon arousal from prolonged bear hibernation?

💡 Explanation

Upon arousal, accumulated metabolites cause profound vasodilation because oxygen demand increases dramatically after a period of inactivity, flooding tissues and drastically dropping systemic blood pressure. Therefore systemic hypotension results, rather than vasoconstriction or tamponade conditions which require different homeostatic disruptions or structural failure modes.
