Which chamber of the heart receives blood from the body?

The right atrium is the correct answer because it is specifically designed to receive deoxygenated blood from the body through two major veins: the superior vena cava and the inferior vena cava. This chamber plays a crucial role in the circulatory system by collecting blood that has circulated through the body and is low in oxygen before passing it into the right ventricle. Once in the right ventricle, this blood is then pumped to the lungs for oxygenation.

In contrast, the left atrium receives oxygenated blood from the lungs via the pulmonary veins, the left ventricle pumps this oxygen-rich blood to the rest of the body, and the right ventricle sends deoxygenated blood to the lungs. Understanding the specific functions of each chamber is vital for a comprehensive grasp of the heart’s role in the circulatory system.
