Atrium
Ventricles
Explanation:
The upper chambers of the heart are called atrium whereas the lower chambers are called ventricles.
The heart is at the center of the circulatory system which moves blood round the body.
At the atrium, blood returning from the lungs and body parts fills up this part of the heart. It is divided into a left and right atrium. The ventricles pumps blood out of the heart into the body parts and lungs. It has a thicker wall.
