What are the upper chambers of the heart called?

  1. Ventricles

  2. Atria

  3. Valves

  4. Septum

The correct answer is: Atria

The upper chambers of the heart are called atria. The heart consists of four chambers in total: two upper chambers known as the atria and two lower chambers known as the ventricles. The atria receive blood returning to the heart from the body and lungs. The right atrium collects deoxygenated blood from the body, while the left atrium receives oxygenated blood from the lungs. This division allows the heart to efficiently manage the flow of blood throughout the circulatory system. This distinction between atria and the other structures in the heart, such as valves or the septum, is essential for understanding how the heart functions as a pump.
