The atria (singular atrium)
The main central room in a Roman house, -or one of the two upper cavities in the heart.
The two cavities in the heart, known as the atria and ventricles, are part of a larger structure known as the heart itself. Additionally, larger blood vessels such as the aorta, which carries oxygenated blood from the heart to the body, and the vena cava, which brings deoxygenated blood back to the heart, are larger than these cavities. Furthermore, the entire circulatory system, which includes arteries, veins, and capillaries, is also larger than the heart's cavities.
