The human body has four upper chambers within the heart, consisting of two atria (the left and right atrium) and two ventricles (the left and right ventricle). The atria are the upper chambers that receive blood, while the ventricles are the lower chambers that pump blood out of the heart. Overall, there are two upper chambers if referring specifically to the atria.
The walls of the upper chambers are thinner than those of the lower chambers. The upper chambers don't need to generate as much pumping force as the ventricles.
