The atrium (Latin: ātrium) or auricle is the upper part through which blood enters the ventricles of the heart.

There are two atria in the human heart. The left atrium receives blood from the pulmonary (lung) circulation. The right atrium receives blood from the venae cavae (venous circulation).^[1]
