Which part of the heart receives deoxygenated blood from the body?

The right atrium is responsible for receiving deoxygenated blood from the body. Blood returns to the heart through two major veins: the superior vena cava and the inferior vena cava. The superior vena cava drains blood from the upper parts of the body, while the inferior vena cava collects blood from the lower regions. Once this deoxygenated blood enters the right atrium, it is then directed into the right ventricle, which subsequently pumps it to the lungs for oxygenation.

This anatomical and physiological function is crucial for maintaining the proper circulation of blood throughout the body. Understanding the flow of blood through the heart's chambers helps clarify how oxygenated and deoxygenated blood circulates, illustrating the essential role the right atrium plays in the cardiac cycle.
