FALSE.

The right atrium’s where the process begins, where the CO2 Blood enters the heart.

Through the tricuspid valve, to the right ventricle, the pulmonary artery, and lungs.

Once inside the lungs, it dumps its carbon dioxide and picks up its oxygen supply.

Then it’s back to the heart through the pulmonary vein, through the atrium and left ventricle.
