What structure in the heart receives deoxygenated blood from the body?

The right atrium is the chamber of the heart responsible for receiving deoxygenated blood from the body. This blood is carried to the heart through the superior and inferior vena cavae, which bring blood back from the upper and lower parts of the body, respectively. Once the deoxygenated blood enters the right atrium, it flows through the tricuspid valve into the right ventricle, where it will then be pumped to the lungs for oxygenation.

Understanding the function of the right atrium is crucial in grasping the overall flow of blood through the heart and the circulatory system. It plays a key role in ensuring that deoxygenated blood is directed appropriately for reoxygenation, which is essential for maintaining the body's oxygen levels.
