Which part of 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 returns to the heart through two large veins known as the superior vena cava and the inferior vena cava. Once collected in the right atrium, the blood is then pumped into the right ventricle, which subsequently sends it to the lungs for oxygenation. This process is a crucial part of the circulatory system, as it ensures that blood depleted of oxygen is correctly handled and sent to be replenished with oxygen before continuing its journey through the body.

The left atrium, on the other hand, receives oxygenated blood from the lungs. The left ventricle is responsible for pumping oxygenated blood out to the body after it has passed through the left atrium. The right ventricle, while it handles deoxygenated blood like the right atrium, does not receive it; rather, it pumps it out to the lungs. Thus, the right atrium plays the essential role of collecting deoxygenated blood coming back from systemic circulation.
