The name of the chamber is the right ventricle. Drains is the wrong term . . . The right ventricle pumps deoxygenated blood to the lungs!
The right chamber pumps blood to the lungs to get oxygen.
The left atrium is the chamber that receives oxygenated blood returning from the lungs.
The inferior vena cava brings blood back to the heart from the lungs.

the chamber of the heart which receives oxygenated blood from the lungs is the left atrium
The right ventricle sends deoxygenated blood to the lungs.
Your left atrium receive oxygenated blood from the lungs.
Oxygenated blood returning from the lungs flow into the left atrium.
The left ventricle is the thickest and most powerful chamber of the heart. It has to pump blood further (to the body) than the right ventricle (to the lungs).
the heart does not give the body it's oxygen it is the lungs. The heart is used to pump the blood to the lungs to pick up oxygen and then to pump the blood throughout the body and add oxygen to the blood cells.
There are two such chambers; they are the ventricles. The right ventricle sends blood out of the heart and to the lungs; the left ventricle sends blood out of the heart and into the body and heart muscle tissue.
A robo-heart works as it does because the motor compresses the left chamber to pump the oxygenated blood out into the body. At the same time the right chamber sucks in the deoxygenated blood to fill it up. then the right chamber is compressed to pump deoxygenated blood to the lungs. The left chamber opens to collect oxygenated blood from the lungs. Special sensors detect the body's movement and changes pace of the beat.
