What are the lower chambers of the heart called?

Explanation:
The lower chambers of the heart are the ventricles. This is the part of heart anatomy that specifically refers to the two pumping chambers: the right ventricle sends blood to the lungs, and the left ventricle sends blood to the rest of the body. In contrast, the upper chambers are the atria, which receive blood returning to the heart. The aorta is not a chamber at all—it's the main artery that carries blood away from the left ventricle to the body. So, the term ventricles identifies the lower, pumping chambers responsible for moving blood onward from the heart.
