Answers: heart attack is when blood flow is restricted from passing through the heart, regularly due to excess cholesterol built up in the arteries. When the blood doesnt jump through, the heart pumps harder and eventually seizes. A stroke is when a piece of the cholesterol buildup contained by the artery breaks off and flows to the brain. It explanation that certain slice of the brain to lose blood, and that part of the brain dies. Often resulting within paralysis.
and cardiac arrest is when the heart breaks rhythm and stops pumping efficiently.
