A Human Heart Diagram

This human heart diagram shows your heart 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.

Your heart itself is made up of two main parts. The heart muscle and the valves. There are two valveson each side of your heart 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 in your heart are are powerful pumping chambers that push your blood into the main blood vessels.

Your heart muscle supply the pumping power that is essential to keep your circulation going. The lefy ventricledoes the most amount of work in maintaining circulation to all parts of the body except your lungs. It is the thickest and most powerful heart muscle.
