The atria (singular: atrium) or auricles.

Explanation:

The heart is divided into four chambers; the two upper chambers are the left atrium (auricle) and right atrium (auricle), while the two lower chambers are the left ventricle and right ventricle.

The left atrium receives de-oxygenated blood from the body via the veins (the inferior and superior venae cavae), while the right atrium receives oxygenated blood from the lungs via the pulmonary veins.
