The human heart is responsible for pumping blood through your body. It
would be impossible to live without it. That’s why heart attacks are so dangerous.
Every time a healthy heart beats, it is sending blood throughout the body. The
average human heart beats about seventy-two times per minute. Electricity causes
the four parts of the heart to work together to create heartbeats.
A heart attack happens when the blood supply cannot get in or out of the
heart. Usually, this happens when fat and white blood cells get clogged in an artery.
An artery is a pathway to the heart. When blood flow to the heart is stopped, heart
cells begin to die. People feel chest pain and sweat when they’re having a heart
attack. Often they have trouble breathing or begin vomiting.
Heart attacks are the leading cause of death all over the world, but there are certain things we can do
to prevent them from happening to us. First of all, eating healthy and exercising can stop heart disease. Also,
we should not smoke. Smoking increases the chance of having a heart attack.
