Which chamber receives oxygenated blood from the lungs?

Explanation:
After gas exchange in the lungs, the oxygen-rich blood returns to the heart through the pulmonary veins and enters the left atrium. The left atrium acts as the receiving chamber for this oxygenated blood, which then passes to the left ventricle to be pumped out to the body. In contrast, the right atrium collects deoxygenated blood from the body, and the right ventricle sends blood to the lungs.
