The upper chambers of the heart are called the **atria**. The heart has four chambers: two upper chambers known as the atria (singular: atrium) and two lower chambers called the ventricles. The right atrium receives deoxygenated blood from the body, while the left atrium receives oxygenated blood from the lungs.

The atria play a crucial role in the heart's function by receiving blood and then contracting to push that blood into the ventricles, which in turn pump it out to the lungs and the rest of the body. Other options provided in the multiple-choice answers, such as auricles, AV valves, and septa, refer to different structures and components of the heart, but they do not represent the upper chambers.

In summary, the correct answer is **atria**.
