Atria is the receiving chamber and it is located at the top while ventricles are the one responsible for pumping blood out of the heart either to oxygenate the blood or to deliver it into our systems and it is located at the bottom part of the heart
atriums and ventricles are apart of the four parts of your heart ventricles are on the bottom and atrium's are on the top hope this helped =D
the upper two are atria and the bottom two are ventricles

TRUE
The Atria and Ventricles are parts of the heart not the blood. The Atria is the upper chambers of the heart and the Ventricles are the lower chambers of the heart.

The atrioventricular valves are located between the atria and the ventricles. The semilunar valves are located between the ventricles and the arteries leaving the heart.
