What chamber of the heart receives deoxygenated blood from the body?

The right atrium is responsible for receiving deoxygenated blood from the body. Blood returning from the body, which has delivered oxygen to tissues and collected carbon dioxide and other waste products, enters the right atrium through two main veins: the superior vena cava and the inferior vena cava. From the right atrium, blood flows to the right ventricle, which then pumps it toward the lungs for oxygenation. This pivotal role of the right atrium is essential in the circulatory system, facilitating the continuous flow of blood and maintaining the separation of oxygenated and deoxygenated blood throughout the heart's functioning.
