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.
Two. Left and right atrium
The lower chambers of the heart have a different function than the upper chambers. The lower chambers pump the blood out of the heart into the body and lungs.
The two upper chambers of the heart are called the atria. They receive blood from the body and the lungs and help to pump it to the lower chambers of the heart.
Two - the left and right ventricles. The upper chambers are the left and right 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.
