Which chamber of the heart receives deoxygenated blood?

The right atrium is the chamber of the heart responsible for receiving deoxygenated blood. This blood comes from two major veins: the superior vena cava and the inferior vena cava. The superior vena cava drains blood from the upper body, while the inferior vena cava drains blood from the lower body. Once the right atrium fills with deoxygenated blood, it then contracts and sends the blood to the right ventricle, which subsequently pumps it to the lungs for oxygenation.

Understanding the flow of blood in the heart is crucial, especially how deoxygenated blood is managed. The left atrium, on the other hand, receives oxygenated blood from the lungs, and the left ventricle is responsible for pumping oxygenated blood to the rest of the body. The right ventricle, while it does deal with deoxygenated blood, receives it from the right atrium rather than being the receiving chamber. This highlights the right atrium's unique role in the circulatory system.
