Take care of your heart
The human heart is a pear-shaped,
fist-sized body organ with muscular walls. It controls the flow of
blood to every part of your body. It’s located just left of center in
your chest, right behind your breastbone (sternum). And although the
heart weighs less than a pound—every minute or so, its strong pumping
action can cycle all the blood in your body through its chambers.
What makes your heart pump? To pump blood throughout your body, your heart contracts (squeezes) and relaxes in a rhythm. A natural“pacemaker,” the sinoatrial (SA) node, sits at the top of the right atrium and controls this rhythm by sending out a series of electrical impulses. The impulses travel from the SA node down an electrical pathway along the heart muscle walls, causing the heart to contract. The muscular heart wall is called the myocardium. The myocardium serves as a strong pump to move blood through your blood vessels.
