what distinguishes a heart attack from heart failure.\na. a heart attack results from poor blood flow, while heart failure involves a total interruption of blood flow.\nb. both heart attack and heart failure result in heart tissue death, but more tissue dies as a result of heart failure.\nc. heart tissue dies during a heart attack, while heart failure results in systemic oxygen deficiency.\nd. heart failure results in body tissues receiving such a high level of oxygen that it is toxic.
Answer
Answer:
C. Heart tissue dies during a heart attack, while heart failure results in systemic oxygen deficiency.
Brief Explanations:
A heart - attack occurs when blood flow to part of the heart is blocked, causing heart tissue death. Heart failure is a condition where the heart can't pump enough blood to meet the body's needs, leading to systemic oxygen deficiency. Option A has incorrect definitions as heart failure doesn't involve total interruption of blood flow. Option B is wrong because more tissue doesn't necessarily die in heart failure compared to a heart - attack. Option D is incorrect as heart failure causes oxygen deficiency, not high oxygen levels.
