__**How the heart works?**__

 * The heart is a powerful muscle that is located in the chest just behind the rib cage it is no bigger than your fist. The heart is different from other muscles it never gets tired. Its main job is to pump blood through so the nutrients and oxogen in the blood can get to the organs and tissue that need them.

The heart is made of two pumps one on the left side and one on the right. Both sides include ventricles and atrium. The ventricles pump the blood through the body and the atrium brings it back to the heart and passes it to to the ventricles which pump the blood back out.

When your brain sends a signal for the heart to Beat the right atrium fills with the used blood that has been through the body and needs to go to the lungs for more oxogen. The left atrium fills with fresh blood from the lungs that is ready to go back through the body. The atrium push blood to the ventricles, when all the blood is in a ventricle the valve between the atrium closes and the ventricle squeezes the blood out of the heart and into the body. the right ventricle pumps old blood to the lungs and the left ventricle pumps fresh blood into your body so it can circulate.

The heart is the most powerful muscle in the human body. It keeps you alive and does almost everything for your body.**
