question
Explain what distinguishes a stroke from a heart attack.
answer
ANSWER:
Responses will vary. A sample response follows: Both strokes and heart attacks occur when the blood supply to that part of the body is blocked or interrupted. Strokes occur in the brain, while heart attacks are specific to the heart muscle. Both can be caused when blockages cut off the blood supply and the tissues starves for oxygen and other nutrients. Strokes can also occur when the pressure in a blocked artery causes it to burst and the blood leaks into the brain.
