Human Heart Diagram

Your "ticker" is about the size of your clenched fist. It’s not as big as you may think, but it does a mighty job. It is like a twin pump and is divided into two sides.

It is made up of two main parts. The cardiac muscle and the valves. There are two valves on each side and they make sure that your blood flows in the correct direction.

Each side of your heart is made up of two chambers, the atrium and the ventricle. The atrium receives the blood returning to its side and allows it to flow into the ventricle during the relaxation phase in pumping.

The ventricles are are powerful pumping chambers that push your blood into the main blood vessels.

Your cardiac muscle supplies the pumping power that is essential to keep your circulation going.

The left ventricle does the most amount of work in maintaining circulation to all parts of the body, except your lungs. It is the thickest and most powerful muscle.
