What does the left atrium do?

Explanation:
The left atrium’s job is to receive the blood that comes back to the heart from the lungs. Oxygen-rich blood travels from the lungs through the pulmonary veins and enters the left atrium, where it collects before moving on to the left ventricle to be pumped to the body. The other descriptions refer to the roles of the other chambers: pushing blood to the lungs is done by the right ventricle, collecting blood from the body is the right atrium, and pushing blood to the body is the left ventricle.
