About the Atria
- The atria are separated from the ventricles by heart valves.
- The heart has two atria. A right atrium and a left atrium
- The right atrium receives deoxygenated blood from the body through a vein called the Vena Cava and pumps it into the right ventricle.
- The left atrium receives oxygenated blood from the lungs through a vein called the Pulmonary Vein and pumps it into the left ventricle.
