Q

How does the circulatory system work?

A

Blood enters the left atrium
The atrium contracts and forces the blood into the left ventricle
In between the atrium & ventricles there are special structures called valves
The valves between the atria and ventricles stop blood back flow
When the ventricles fill with blood they then contract and force blood into strong muscular tubes called arteries
The parties carry the blood away from the heart
Then the veins carry the blood back to the heart
