What is a heart attack?
The heart is a muscular pump that’s a little larger than your fist. It’s one of your most important muscles as it pumps blood all over your body through the circulatory system. Your blood carries oxygen, which is needed by every cell in your body, all the time. Your heart pumps oxygen-rich blood from the lungs to the heart, and then on to the rest of the body.
