Is the right atrium oxygenated or deoxygenated?

Understand the Problem

The question is asking whether the blood in the right atrium of the heart is oxygenated or deoxygenated. The right atrium receives deoxygenated blood from the body through the superior and inferior vena cavae.

More Information

The right atrium receives deoxygenated blood from the body and passes it to the right ventricle, which then sends it to the lungs for oxygenation.

Tips

A common mistake is to confuse the right atrium with the left atrium, which receives oxygenated blood from the lungs.
