Which chamber of the heart pumps oxygenated blood to all tissues of the body?

Explanation:
The chamber that pumps oxygenated blood to all tissues is the left ventricle. Oxygen-rich blood returns from the lungs into the left atrium, moves into the left ventricle, and is then forcefully ejected into the aorta to reach every body tissue. The left ventricle has a thicker muscular wall because it must generate the high pressure needed for systemic (body-wide) circulation. In contrast, the left atrium collects oxygenated blood, the right ventricle sends blood to the lungs, and the right atrium collects blood returning from the body—we don’t rely on them to push oxygenated blood to the entire body.
