atrium
The lower chambers of the heart are the left ventricle and the right ventricle.
The heart has four chambers: the right and left atria, which are the upper chambers, and the right and left ventricles, which are the lower chambers.
If I am not wrong the lower two chambers of the heart are called as ventricles i.e. left ventricle and right ventricle while the upper two chambers of the heart are called as atria( plural of atrium) i.e. left atrium and right atrium.
no, the superior chambers of the heart refer only to the left and right atria. the left and right ventricles would be considered the inferior chambers of the heart.
The human heart has four chambers. The atria are the upper chambers, and the ventricles are the lower chambers.
