Which chamber collects deoxygenated blood from the body before it flows to the right ventricle?

Explanation:
Deoxygenated blood from the body returns to the heart and first enters the chamber on the right side that serves as the receiving chamber for systemic venous return. It collects blood through the superior and inferior vena cavae and then passes it to the right ventricle via the tricuspid valve. From there, blood is pumped to the lungs to become oxygenated. The left atrium, in contrast, collects oxygenated blood from the lungs; the right ventricle pumps to the lungs; and the left ventricle pumps to the body.
