Answer:
There are two atria in the human heart – the left atrium receives blood from the pulmonary (lung) circulation, and the right atrium receives blood from the venae cave (venous circulation). The atria receive blood while relaxed (diastole), then contract (systole) to move blood to the ventricles.
